A calm take on the difficulties with preventing terrorism

Many good points made here at Vox.

Oh, and as expected, lots of US websites are saying Trump may well have completely killed his desired travel ban by his stupid use of tweeting.

I also like this critique of Trump's use of fear, in The Atlantic:

Trump is the panic president, bearing a radically opposed message: Fear is not only acceptable, but necessary. Rarely does one see a leader, much less the leader of a liberal democracy, actively embracing, even calling for, panic. But this is Trump’s response, ridiculing Khan’s plea for calm among Londoners. If it is little surprise to see tired demagogues like Lou Dobbs do this, it is distressing to see it in the president of the United States. (There may be a connection—Trump’s rhetoric seems to often derive directly from Fox, Dobbs’s employer.)

This is not a new tendency for Trump. It has been evident since he announced his candidacy almost two years ago, in which he claimed (without substantiation) that unauthorized immigrants were bringing a crime wave with them over the border. It runs through his doomsaying acceptance speech at the Republican National Convention in Cleveland last summer, on to his pronouncements of “American carnage” in his inaugural address, and in his repeated, dishonest claims of a nation in chaotic thrall to crime. It is also central to his claim that the only way to stop terrorism in the United States is to cut off Muslim immigration, even if political and legal realities have forced him to scale back that promise.

Trump’s embrace of panic is instrumental: By first instilling fear, he can then build himself up as the solution, as he did in his RNC speech when he declared, “I alone can fix it.” But panic is a dangerous force, not always controllable by those who whip it up in the first place.  

As for the feud with Khan, the London PM:

Khan poses a particular challenge to Trump’s panic-fueled approach on two levels. For one, his appeal to calm stand at odds with the president’s desire for greater hysteria. But for another, Khan himself represents a threat to that political message. If a Muslim like Khan can win the mayorship of a city like London, and if he can win acclaim as a strong leader who upholds liberal democracy, it undermines the president’s fear-mongering about absorption of Muslims into Western society.

Now that’s something for Trump to fear.

 But large slabs of the Right are currently too stupid to see this.
