American Citizens Risk in War Areas

I am sorry about the death of Kayla Mueller, a U.S. ISIS hostage apparently killed in a Jordanian airstrike on Syria. However if she had not been there, she would not have been killed.
I covered this situation in a previous blog on 12/7/14. At that time, I said the following:
"The question seems to be what do you do to protect American citizens in dangerous parts of the world? It's not an easy one to answer, but I think I can offer clarity on the subject.
The first thing to consider is whether a particular country is dangerous to American citizens. We can easily pick out a few that are not dangerous, such as Canada, Great Britain, France, Germany, and Italy. Some of the clearly dangerous ones are Iran, North Korea, and Libya. Some appear to be marginal, such as Mexico, Cuba, Lebanon, and Israel. However, I don't think that's specific enough.
I believe the United States government should designate which countries of the world are unsafe for Americans to travel and work in. Travel would mean entry to the country for business reasons, family contacts, tourism, missionary and other religious work. Perhaps the best test of whether a country is dangerous for Americans is whether the United States maintains a working embassy with minimal security in the country.
If a country is on the dangerous list, the position of the United States should be that Americans are not restricted from entering or operating within the country, but the United States government will take no extraordinary means to protect them or save them from further harm if captured or detained. Persons excluded from that position would be all employees of the United States government, including military personnel, federal representatives and congressmen, State Department officials, spies, or persons engaged in any activity when they are on the federal government payroll."
Therefore, my position is that Kayla Mueller died as a result of a poor decision to her part to be in Syria. However, the federal government is not doing its job of properly advising citizens traveling abroad of the dangers that might be involved.
