WWI & WWII were won by Democrats also.
Korea was a lost by Eisenhower(R)
Vietnam was actually started by Eisenhower(R) and escalated by those you mentioned and Nixon(R) ended it by surrendering.  
Desert Storm was not a victory so another Republican loss.
OIF also losing and Republican.

So far the Republican s have won 1 and lost 4. 

You aren't very good at this.
