A couple of days ago the US Secretary of State Condoleezza Rice, in a news conference stated that more than sixty countries have offered assistance to the US, but when press by reporters she admitted that the American Government has not accepted any foreign aid.
I don’t think that American pride and ego will allow them to accept much foreign help. Their politicians would see foreign aid as more of an embarrassment then as assistance. However, one can expect in the near future, that the right wing media will attack all foreign governments for their “lack of response or assistance” while bragging about all the foreign aid that the US gives around the world.
If one wants to help our friends to the south, one can send cash to the Canadian Red Cross, who will forward it to the American Red Cross.
