A question

A story in the IHT about how schools and places of learning have increasingly the target of violence in Baghdad:

In the past month, according to Interior Ministry officials, primary and secondary schools in and around Baghdad have been targets at least six times. In some cases, gunmen ambushed schools during classes and guards fought them off.

In other cases, mortar shells struck, killing 10 at Al Gharbiya, for example, a secondary school in central Baghdad.

Several principals and teachers have been kidnapped and killed, a pattern of terror that started with university professors and seems to have trickled down the educational chain.

Can the "withdraw now" crowd explain how coalition troops leaving Baghdad is going to assist the school kids?
