I thought Cuba was a popular US holiday destination?
What I mean is a popular holiday destination for US citizens not a popular holiday destination in the USA.
Nope. Hasn't been the case since the Cuban revolution. There are significant restrictions on the ability of US citizens to travel to cuba. See:

Regarding racial profiling. The reality is that our security resources will always be limited. So we have to prioritize. Young arabic men performed terrorist actions in Munich '72, the Geneva OPEC oil ministers conference, Lockerbie, TWA 847, Achille Lauro, the first World Trade Center bombing, Sept. 11, USS Cole, Dahran air base bombing, Beirut marine barracks, Beirut embassies (US & French), etc., etc. So, should we focus our attention on 85-year-old Polish grandmothers? Or should we focus our attention on young arabic men?
