That would be Senators McCain, Menendez, and Levin, who have urged Obama to take some decisive actions in Syria.
Google "AIPAC political contributions US Senate" and you'll see that these three US Senators are among the leading recipients of AIPAC cash.
This story tells you a few things about the Senate and also about AIPAC.
It's not news that a goodly part of the Senate is bought and paid for by AIPAC.
But it tells you how much AIPAC is a front for the Likud faction rather than being the "pro-Israel" lobby it purports to be.
Likud is most definitely not Israel.
Does anyone who is truly "pro-Israel" imagine that arming a bunch of Islamist fanatics across the border will enhance the security of Israel?
Giving anti-tank and anti-aircraft missiles to the Jabhat al-Nusra will enhance Israel's security?
Of course not, and the Likudniks are fully aware of that.
This is not about security; this is about the war that the war party in Israel clamors for non-stop. The big war that will allow Likud to clear the West Bank and Gaza with the blades of the IDF's Caterpillars.
The agenda is simple. Arm the fanatics in Syria. They will attack Israel sooner or later with their advanced armaments. Then the world will be sympathetic as the IDF clears the occupied territories once and for all.
That is the Likud agenda, and that is the agenda AIPAC and their US Senators are promoting.
What could possibly go wrong?
