I agree it's a bit of a stretch, but only a bit. Had Israel not gotten the USA on board with the attacks on Iran, I do not think gas prices would be much above their standard seasonally- and inflation-adjusted level, unlike where they have been since the "war" started.
So I consider the "solely" to be more than just "a bit" of a stretch. There's blame enough to go around, but a massive chunk of the blame rests on the White House.
Yes to the first question, and no to the second.
Yes, full stop. Israel attacked Iran before USA attacked Iran.
This isn't conjecture, both of these presidents have been openly operating for Israel. Biden even went on live tv and lied about seeing 40 beheaded babies.
You basically have Tomas Massie and Rashida Tlaib as the only mainstream politicians that are actually standing up to the Zionist takeover of our government. It's hard to say what the way out of this mess looks like, but voting for a Zionist in Zionist controlled elections is not it.
Tlaib is one of the four most-extreme-left members of the House. I claim that that makes her not mainstream, for any reasonable definition. She sure is not in the mainstream of the House!
