You do know that Finkelstein is anti Israel, who got mauled over his accusations against Alan Dershowitz. He also attacked holocaust survivors, He was also denied tenure at Depaul University, because of his behavior and views.
I take his comments with a huge grain of salt.
This is just a lovely quote by him as well
To my thinking the honorable thing now is to show solidarity with Hezbollah as the US and Israel target it for liquidation. Indeed, looking back my chief regret is that I wasn’t even more forceful in publicly defending Hezbollah against terrorist intimidation and attack.
