OK, lets look at what Trump disclosed -- According to The Washington Post, Trump described highly classified details of an Islamic State threat related to using laptop computers on aircraft. He also reportedly revealed the city in the Islamic State's territory where the U.S. partner detected the threat.  --- So everybody who is complaining is ignoring the obvious:
1.  Telling another country, even though they may be an enemy, to be careful of laptops on aircraft thereby saving innocent lives.
2.  Telling a country who is supporting a regime where terrorists are operating unchecked.  
You can complain about Trump but not on this issue unless you think this terrorist info should not have been shared.
