Nothing in the post you are referencing came off as antisemitism. Please do not conflate the arming of a militaristic apartheid regime with criticism of blank checkbook legislating.
standard israeli psyop tactic: use jewish people as human shields from criticism directed at the state of Israel by trying as hard as possible to conflate antisemitism with negative sentiment towards israel.
The gp only mentioned Israel. Actual antisemitism is common enough that it is counterproductive to use the term so loosley.
The antisemitic Claude puts the total US grants (= gifts) to Israel in the past 5 years to $33 billion, which my antisemitic calculator puts at $6.6 billion/ year. Of course these gifts allow Israel to fund its own healthcare while it bombs other people for free.
