umm I am not sure but I think it's option A
I believe it is supply shock
When we did the intervention we also set ourselves up for disaster due to putting a border on Mexico making it more attractive to come illegally thru America and we deport alot of them what's hypocritical about that is if we had not put a border and not Intervened into Mexicos business, America and Mexico would have hashed out a proper plan and have made the legal idea of moving to America the only reason to go there.
