Wow have times have changed. Imagine an internet post during Harry Truman's war (we lost about 50,000 in three years) in Korea asking why four Americans were wounded. Imagine a internet post during LBJ's war in Vietnam asking why four Troops were wounded. A more important question is why nobody on the left asked that question during Barry Hussein's administration.
I served in the military
Vietnam was not necessary--the communist DID win and guess what?--the US is still here!!
my dad fought in Korea--that was unnecessary.....
the communist won in Cambodia also and we have the Cuba aspect....
most of these insignificant conflicts were/are unnecessary to get involved in
