And don’t tell me that we should just stop all flights from Africa to the US. That would make things worse (as pointed out by Jon Stewart and others). Besides, it wouldn’t stop anyone who really wanted to fly to the US, because they could just fly somewhere else, then fly to the US.
The truth is that we should have helped Africa prevent this outbreak in the first place. In fact, one of the few things that Dubya did that I applaud wholeheartedly was his work helping Africa.
