America media organisations seem reluctant to re-visit the question of why Trump wants Iran to have a nuclear deal again after quashing the Obama one in 2018. This site gives some of the background on the Obama deal.
It seems reasonable to assume that the original scrapping was all to do with Netanyahu getting into Trump's ear that the Obama deal wasn't good enough, even though it was going to keep things under control for a decade at least. Trump complied, which Netanyahu knew meant that Iran could have a few years of doing what they want, so that Israel could then claim justification to try to take out the nuclear facilities (even though I think it has always been claimed they were situated in locations pretty impossible to take out completely with normal munitions?).
Why Trump started talking about wanting a treaty again this year, before the current Israeli attack, is unclear - but I suspect the best guess would be that it was under pressure his new "pals" in Saudi Arabia and adjacent countries who don't care for Iran either. And there has been talk of Trump being unhappy with Netanyahu doing whatever the hell he wants in Gaza. Just as he now complains about Putin "going crazy".
In other words, seems very likely that Trump got played, and will continue to be played.
Update: Thomas Friedman in the New York Times sets out a "smart" way to end the fighting, which seems full of high hopes that are very unlikely to come to pass. Here's his idea:
There are only two ways to finish off
this problem once and for all. One is for Israel to permanently occupy
the West Bank, Gaza and all of Iran, as America did to Germany and Japan
after World War II, and try to change the political culture. But Israel
has no chance of occupying all of Iran, and it has occupied the West
Bank for 58 years and still has not wiped out Hamas’s influence there —
let alone secular Palestinian nationalism. That is because Palestinians
are every bit as indigenous as the Jews in their homeland. Israel will
never “once and for all” them into submission, unless they kill every
last one.
The only way to even get
close to ending the Israeli-Palestinian conflict “once and for all” is
by working toward a two-state solution. Which brings me to what Trump
should do now regarding Iran. He says he still hopes “there’s going to
be a deal.” If he wants a good deal, he should declare that he is doing
two things at once.
One, that he will
equip Israel’s Air Force with the B-2 bombers and 30,000-pound
bunker-buster bombs and U.S. trainers that would give Israel the
capacity to destroy all of Iran’s underground nuclear facilities unless
Iran immediately agrees to allow teams from the International Atomic
Energy Agency to disassemble these facilities and to have access into
every nuclear site in Iran to recover all fissile material that Tehran
has generated. Only if Iran completely complies with these conditions
should it be allowed to have a civilian nuclear program under strict
IAEA controls. But Iran will comply only under a credible threat of
force.
At the same time, Trump should declare
that his administration recognizes the Palestinians as a people who have
a right to national self-determination. But to realize that, they must
demonstrate that they can fulfill the responsibilities of statehood by
generating a new Palestinian Authority leadership that the United States
deems credible, free of corruption and committed both to effectively
serving Palestinian citizens in the West Bank and Gaza and to coexisting
with Israel.
Trump must also make
clear, though, that he will not tolerate the rapid settlement expansion
and one-state reality that Israel is now creating, which is a
prescription for a forever war because Palestinians in the West Bank and
Gaza won’t disappear or “once and for all” give up their national
identity and aspirations. (At the end of May the Netanyahu government approved 22 new Jewish settlements in the occupied West Bank — the largest expansion in decades — which is simply insane.)
To that end, Trump could also say that
his administration will be committed to sponsoring peace talks for a
two-state solution — with the Trump peace plan
for a pathway toward two states from his previous presidency as the
minimum starting point but not ending point. That, the parties
themselves must negotiate directly.
To
be ready to out-crazy the crazies has been a necessary condition for
Israel to survive in the Middle East, but it is not a sufficient one. As
the Gaza war demonstrates, that strategy just begets more of the same.
Even if it seems unfair at times, even if it seems naïve at times, a
peace-loving nation has to keep exploring alternatives and pairing force
with diplomacy. It’s not only the best policy for Israel vis-à-vis the
Palestinians; it’s also the best way for Israel and America to isolate
Iran.
As such, if Trump really wants
to forge peace in the Middle East, which I believe he does, America must
not become Netanyahu’s captive or Iran’s patsy. The United States has
no interest in making Israel safe for messianic expansion or Iran safe
for nuclear messianism. Trump must ignore the dangerous, knee-jerk
isolationism of JD Vance. And he must eschew the equally foolish
Netanyahu-can-do-no-wrong advice of G.O.P. armchair generals and
evangelicals. Neither serves U.S. interests or credibility in the
region.
And I guess this plan might just work - were it not for Trump, his nutjob base, his nutjob advisers, Netanyahu, and the Ayatollah.
Update 2: Speaking of Trump's "advisers" - it seems there is some serious in-fighting within the MAGA group of "celebrity" talking heads:
Conservative pundit Tucker Carlson has fired back at MAGA figures upset that he accused President Donald Trump of abandoning the “America First” movement.
Carlson,
56, ranted for 45 minutes on Steve Bannon’s show on Monday, attacking
some of his former Fox News colleagues, Rupert Murdoch, and anyone who
suggests he is anti-semitic for opposing U.S. support to Israel for its
conflict with Iran.
“You’re not going to convince me that the
Iranian people are my enemy,” Carlson said. “Again, we’re going down
this here—here’s who you are required to hate. It’s Orwell, man. I’m a
free man. You’re not telling me who I have to hate. I’ll decide who I
like and don’t like.”
Carlson criticized
Trump last week for being “complicit” in Israel’s attack on Iran. He
suggested the president betrayed swing-state voters who elected him in
part because he promised to end U.S. involvement in wars abroad.
Carlson’s plea for Trump to “drop” support for
Israel and its prime minister, Benjamin Netanyahu, opened him up to
intense criticism from his former colleagues, including the Fox News
pundit Mark Levin.
A similar outcry came from many MAGA influencers, such as Laura Loomer, who has become an unofficial adviser to Trump in MAGA 2.0.
“Can we stop pretending like @TuckerCarlson
is a true Trump supporter?” Loomer posted to X on Monday. “He has never
publicly apologized for what he said about President Trump. He was
fired by Fox News and then was terrified Trump would torpedo his career
when the texts of him saying he ‘hates Trump’ came out... His fake it
till you make it ‘support of Trump’ got his son a job working in the
White House. This, of course, came after Tucker asked Hunter Biden to
help his son get into college. Real story by the way. Look it up. Who
cares about merit when you have Nepotism, Muslim investors, and Qatari
cash flow? Ammiright?”
Levin wrote that Loomer’s screed was “well said.”
