The ‘lot of flak’ the US is getting is hurting them a lot less than more concrete things like the trade disruptions due to the red sea shipping attacks.
Which also is caused by America not forcing israel to stop their Genocide for some reason…
Of course politicians aren’t solely beholden to israel. There are plenty of other lobby organizations which get what they want because they bribe politicians. Oil lobbies, Agro lobbies, Pharma lobbies etc. Military Industrial lobby of course loves what israel is doing right now.
It’s just that when it comes to israel, the politicians act the way israel wants instead of in a strategically advantageous way for America. There’s not much of a case that can be made for the current government actions other than “Our politicians are bribed by israel”
Past israel did a far better job appealing to politicians to make a case for their existence than current israel though I’ll agree with that. Hasbro game is weak these days.
