I hate to agree with Dianne Feinstein, but I agree with Dianne Feinstein
So how’s about this: Don’t support Israel if we strike Iran, just stay the f@#$ out of the way and let us do what we must.
It is one thing, and proper, to sign mutual defense treaties or have understandings of such with allied nations. It is quite another to put in writing that U.S. soldiers, sailors, marines and airmen will shed blood and be killed if a friendly nation decides to pre-emptively attack another nation. That goes for any friendly nation, not just Israel.
Israel has somewhere in the range of 200 nuclear weapons. It has one of the finest air forces on Earth, and probably the most effective intelligence operation in the Mossad. Israel receives billions of dollars of foreign military aid per year from the U.S. They are more than capable of both defending their country and, should they wish, inflicting crippling damage upon Iran in an offensive strike.
To put it lightly, I would defend my best friend no matter what if he is sucker punched in a bar. If he asked me to promise to back him up no matter what because he wants to sucker punch a smaller guy who ran his mouth a bit... that's a different situation.
Di Fi is lying about the bill. There is no automatic declaration of war.
