Here are a few interesting questions from Libertad Digital's blog:

In addition to surprise among the allies and approval among Spain's enemies, the withdrawal from Iraq of the Spanish troops raises doubts about the real motivations of the prime minister when he made the announcement unexpectedly on Sunday, the second day of his term:

1) If it was a decision based on the conclusions drawn from the secret meeting of Bono (the new Defense Minister) and Rumsfeld and in the impressions they had developed before the Parliamentary debate (Thursday), why wasn't it announced during that debate when, specifically, the leader of the Opposition (Mariano Rajoy) asked Zapatero insistently to confirm his plans regarding the Spanish presence in Iraq?

2) Zapatero promised that he would wait until June 30 to decide whether the troops would stay on; what led him to flagrantly break this promise in the first decision he made?

3) Zapatero said, categorically, there would be no turnover of military command to a UN multinational force (i.e. that the US would not do so); why, then, did he repeat during the Parliamentary debate that he hoped said organization would act as an umbrella for Spanish presence?

4) The Prime Minister has stated that Spain is withdrawing from Iraq in order to continue contributing to the stabilization and democratization of that country: how exactly does he plan to do this?

5) The Prime Minister promised that his new style would be based on dialogue and consensus before making big decisions. What happened to that promise when he presented his first serious decision as a fait accompli, not only to the Opposition in the Parliament but to his own Council of Ministers?

6) What does the Prime Minister plan to do with the Spanish troops stationed in Kosovo, where the international intervention was also made without UN approval?

To which I'd add 7) How likely is it that an instant withdrawal from Iraq was the Communists' and Republican Left's price for their support?
