Doesn't matter though, the US Constitution defines treason:

> Treason against the United States, shall consist only in levying war against them, or in adhering to their enemies, giving them aid and comfort.

This bar is virtually impossible to clear. You'll never get a US court to convict anybody of treason for anything concerning Israel. Espionage sure, but not treason. The last time anybody got convicted of treason for anything in America was for acts committed during WW2, which is the last time America was in a properly declared war.
