It has been "subject to change" without "subject to change" all the time with Israel holding a fame of the currency of choice for the US, subject to an exchange rate of the day.
I see no major problems with supporting Israel at this time.
After we actually attack France, we might consider attacking some of our other putative allies, if we are in a righteous attacking kind of mood.
Israel is not in the most deserving top five contendors list, IMHO.
It certainly makes more sence to hit France first and hard, if we really wanted to punish occasionally faithless allies.
