What Part of "Shall Have the Power To Appoint Ambassadors" Doesn't She Understand?

On the one hand, Speaker Pelosi is unwilling to tamper with the complexity of negotiations seeking the release of 15 British sailors and marines, not even having breathed a word on the subject in the last two weeks--even after the Senate condemned the piracy last Thursday in a single day from the introduction of the resolution to its passage, instead sending her flack out to admire the problem:

"Pelosi’s spokesman, Brendan Daly, said the speaker was reluctant to weigh in on the incident without knowing for sure that such a message would do more good than harm. Daly said the British government had not asked Congress to try to pressure Tehran."

On the other hand, as regards the entirety of U.S. diplomacy vis-a-vis the nation of Syria, she's willing to jump right in and start splicing wires on behalf of captured Israeli soldiers:

“They [the dog-tags] are in my office, I carry them with me today, with the promise that we must never rest until they are all safely at home. And yes, I will mention this to the president of Syria.”

Now, I'm as much in favour of freedom for captured Israelis as anyone else, but by what standard does Pelosi go to bat for the Israelis, but won't even permit a vote on a resolution in support of the British?
