The criticism of Trump - which came from a number of members of his own party - was that he seemed to lack an understanding of how the term has been used historically.
Trump chastised Russian Federation and Iran for supporting "murderous dictators", and noted that Putin had guaranteed a 2013 worldwide agreement for Assad to get rid of all of his chemical weapons.
President Donald Trump could not have chosen two more ominous words - "mission accomplished" - to hail Friday's retaliatory attack on Syria for its chemical weapons attack on civilians. Anyone - and I mean anyone - who has followed the political and policy debate in this country for the last 20 years knows exactly what the words "mission accomplished" conjure up. Standing on the deck of the Nimitz class aircraft carrier USS Abraham Lincoln on May 1, 2003, he proudly announced "major combat operations in Iraq have ended" as a banner that read "Mission Accomplished" hung in the background.
The administration has committed around 2,000 ground troops in Syria. Speaking on French television BFM and online site Mediapart, Macron stressed that the French diplomacy is able to talk with Iran, Russia and Turkey on one side and to the United States on the other side.
Mattis said Thursday evening that the USA had not yet confirmed that the Douma attack - the most recent suspected Syrian chemical weapons attack, on April 7 - included the use of sarin gas.
"It's a tough contradiction for him to sort out", the official said. "Assad has succeeded, at least for the foreseeable future, and he is capitalizing on that". Weeks later, it became apparent that Iraqis had organized an insurgency that would tie down US forces for years.
The U.S. -led operation won broad Western support. "And now you know the full story", Fleisher wrote.
US President Donald Trump addresses the nation on the situation in Syria April 13, 2018 at the White House in Washington, DC. Particularly when in reference to a military strike against a foreign power. In fact, Gen. Joseph Dunford, chairman of the Joint Chiefs of Staff, said no additional attacks were planned.
The phrase also endured, becoming a code word for any mission that was not particularly accomplished, despite a politician's claims to the contrary.
