It's my understanding that countries generally ASK for help before it is given - when it comes to things like natural disasters, etc.
How much aid did the U.S. offer for all the flooding in Europe last week? That's right - NOTHING, because the Europeans don't need it for that disaster, and they didn't ask for any aid.
The U.S. doesn't need any help, and won't be asking for any - that's why you won't see any - no other nefarious reason.
Do you really think that nobody would give aid if the U.S. ASKED??? Of course they would. Countries like the UK have always been there for the U.S., along with a bunch of other allies.
The only people that could provide any assistance that the U.S. could actually use are in OPEC - and I agree with you that THOSE fuckers won't do a thing.
