but in a broad view i wouldn't want to see my brothers supporting the U.S in propping up regime's like in Israel.
Your view on Israel is your own. You are allowed to hold the personal view that Israel is a propped up regime. Other Brothers will hold completely different views. We do not discuss politics as Mason's, nor do we discuss religion in any form that would be considered offensive. If you can accept that, then you will be fine. If you can not, Freemasonry will not be for you. You check your religious and political opinions at the door.
is there any importance to the masons that Israel represents a christian faith over muslim?
Considering both Christian and Muslim faiths have both sprung from Judaic teachings / backgrounds... I wouldn't think so. Freemasons have many Christian Brothers, Muslim Brothers, Jewish Brothers, and also Odenists, Wicken, Deists, Mithra... the list goes on and on. Opinions on these subjects are checked at the door. Believe what you want, but understand every other Brother can believe what they want as well (with the exception of Atheism).
You may be a great guy. You may be famous, or rich, or influential. What you are is the same as any other person looking into Freemasonry, who if applying and found acceptable, will become a Brother no better or worse than any other. We are equals.
