So it took them 'weeks' to come up with an order that, as of now, sanctions just 4 people, none of whom are government officials or even particularly influential.
It's "bold" to issue an executive order against citizens of a friendly foreign country that's a partner in arms development... anything more, could risk being "unfriendly", or even "hostile".
There's definitely a problem when I compare this unfavorably to how much harsher and effective Ronald Reagan was when dealing with the Likuds' wanton violence. Ronald Reagan. The guy who wasn't even principally opposed to some wanton violence thought Israel was crossing the line and stopped them more than once.
