There are lots of options - if you have a few million dollars to pay the lawyers. If you win you get that back. Sometimes lawyers will accept cases on pay only if you win - but generally only if they are sure of winning which this doesn’t seem to me. Still check with a lawyer if you want to consider it.
I don’t have a choice. Either you defend Iran for funding everyone who wants to kill the Jews, or you defend the US and Israel for attacking Iran. There is no middle ground, either way you are defending genocidal maniacs. I hate both options.
