The idea that Israeli lobbyists are singlehandedly "paying off the US' debt" is so patently absurd that I can easily see someone interpreting it as anti-semetic. Criticizing pro-Israel lobbyists is one thing, but when you start implying that Israeli lobbyists literally control the US government, I think you're stepping into clearly anti-semetic territory.
That alongside the wink-wink nudge-nudge "we all know who it is" comment really pushes this post over the edge. You're clearly parroting anti-semetic tropes, intentional or not.
