'I knew they would seize on this but felt it is such a great Military term, it should be brought back.
Bush gave his speech aboard the USS Abraham Lincoln aircraft carrier a little more than a month after United States troops were deployed to Iraq, and it would soon become clear that the mission was, in fact, not accomplished.
'A perfectly executed strike last night.
Trump's declaration of "mission accomplished" after the Syria strike drew widespread comparisons to the "Mission Accomplished" banner that was hung behind former President George W. Bush shortly after the fall of Saddam Hussein in 2003.
However, Syria claimed that 110 missiles were launched in the strikes, and the country's defense systems intercepted majority.
The strike Friday night was in response to a suspected chemical weapons attack by the Syrian regime April 4 against a rebel stronghold outside Damascus in the town of Douma.
In his televised address from the White House on Friday evening, Trump said the US was prepared to sustain economic, diplomatic and military pressure on Assad until the Syrian leader ends what Trump called a criminal pattern of killing his own people with internationally banned chemical weapons.
In May 2003, President Bush stood on an aircraft carrier under a giant "Mission Accomplished" banner and declared that "major combat operations in Iraq have ended" - just six weeks after the invasion.
Later Sunday, Trump sent a letter to congressional leaders informing them in writing of his decision to order the strike.
Trump earlier this month had reluctantly agreed to keep US troops in Syria for an undetermined period of time to defeat ISIS.
Trump's tweet Saturday appeared to be referring to the success of the strike, but whether or not the Assad regime will be deterred from using chemical weapons remains to be seen.
The nighttime assault on Syria was carefully limited to minimize civilian casualties and avoid direct conflict with Russian Federation, but confusion arose over the extent to which Washington warned Moscow in advance. The Pentagon said it gave no explicit warning. "I believe that we took the heart of it out with the attacks. But..."
She added that while the mission in Syria remains defeating the Islamic State, which has seen its grip weaken in the region in recent months, the USA will not allow Assad to attack "innocent Syrian people". In the bigger picture other interests and objectives are at play, and the U.S.is using the plight of the Syrian people to legitimise military intervention, making way for a possible shift in the U.S.'s Syria policy if the situation demands it.
"Good souls will not be humiliated", Assad tweeted, while hundreds of Syrians gathered in Damascus, the capital, where they flashed victory signs and waved flags in scenes of defiance after the early morning barrage.
Has this newfound mission to put an end to Assad's use of chemical weapons been "accomplished" by the airstrikes? He has continued to rail against the war while in office, and his supposed aversion to becoming entangled in unwinnable foreign conflicts led him to declare, just a few days ago, that he wanted to pull all US troops out of Syria.
In his televised address from the White House on Friday, Trump said the US was prepared to keep up the economic, diplomatic and military pressure on Assad until he ends a pattern of killing his own people with internationally banned chemical weapons. The NATO alliance gave its full backing; NATO Secretary-General Jens Stoltenberg said in Brussels that the attack was about ensuring that chemical weapons can not be used with impunity.
