Claiming that a foreign agent supplied money isn’t offensive, but insinuating that a grasroots movement, a foreign agent, and our government is all linked in a global conspiracy, is very offensive.
The US government is perfectly capable of making bad foreign policy all on their own. There may be a foreign agent trying to influence things, but the final policy is ultimately the responsibility of the US government, and the US government alone.
It is far more likely that a US government which is extremely pro-Israel—to the point where it arrests peaceful student protestors for opposing a genocide—that this governments has their own reason to be this extreme. My guess is that they see profits in supporting an antagonizing state—i.e. Israel—in the Middle East. That having this antagonizing state keep the whole region unstable serves some purpose which the US ruling class likes (my guess is oil prices, weapons manufacturing, and inflated influence).
