As please as I am abouit getting back American citizens., this is absolutely the wrong thing to do. NEVER, repeat, NEVER negotiate or make agreements with terrorists. All this will do is let the terrorists know that kidnapping Americans is profitable.
This means that no American tourist would be safe in a Muslim country because they could be seized to be used as a bargaining chip in a future infidels-for-terrorists trade. In particular Americans should avoid traveling to Egypt and other Arab Muslim countries.
