Question: Is this a strawman
Hi! Great question. Straw man makes sense to me, although nowadays we would say "straw person" or some such.
It also seems like a questionable analogy. An analogy only works if the two cases (the US & Israel) are similar in every essential way. The two cases are obviously much different. For example, Mexico is not threatening military action against the US. No one is firing rockets across the Texas border.
Informal logic fallacies don't always fall into neat categories, do they?
In any case, your buddy is making what seems to me to be a very weak argument.
