I am fine if Isreal takes care of it themselves. It is their threat they should deal with it as they see fit.
I agree wholeheartedly, and the American should stay the fuck out of it.
To take it a step further. Everyone must choose an allegiance to a single country, and in this case the American citizenship. If anyone that have a problem with it, then they should get the fuck out of America. And, non of the dual citizenship bullshit.
Thus, any American citizen that leave America to join the IDF, PSF, IRIA, IRCG, Al-Qaeda, or any group/nation beside the USAF should be treated as traitor/terrorists and the violators will be prosecuted to the fullest extent of the law. Unless they relinquish their citizenship prior to join other nation/group of arms, and are not allow to reapply for US citizenship.
And, anyone or organization in the US ask or donate to organizations outside of the US will be deemed as terrorist if the donation is not for humanitarian aids (school, hospital, and feed the hunger are okay, but not arms, churches, banks, businesses, properties, etc...)
IMHO, if you don't want to be an American then get the fuck out of America, because there are plenty of educated and upstanding people that are lining up to come to the great and free nation of the USA, and to become taxpaying American.
