No more foreign wars: that was one of the key promises Donald Trump made to his supporters on the campaign trail to become US president.

In October, while dining at his Trump National Doral golf resort in Miami, the then-Republican candidate Trump said: "What we should do is focus on ISIS. We should not be focusing on Syria… You’re going to end up in World War Three over Syria if we listen to Hillary Clinton.”

No surprise then that today those key supporters who voted for Trump are not that happy with his decision to strike Assad in Syria after a chemical attack in Idlib on Tuesday. And they have taken to Twitter to voice their opposition: here's what some of the more prominent voices have said...

Former KKK leader David Duke:

Editor of Infowars Paul Joseph Watson:

I guess Trump wasn't "Putin's puppet" after all, he was just another deep state/Neo-Con puppet.



I'm officially OFF the Trump train. — Paul Joseph Watson (@PrisonPlanet) April 7, 2017

Conservative commentator Ann Coulter:

Trump campaigned on not getting involved in Mideast. Said it always helps our enemies & creates more refugees. Then he saw a picture on TV. — Ann Coulter (@AnnCoulter) April 7, 2017

Talk show host Laura Ingraham:

Missiles flying. Rubio's happy. McCain ecstatic. Hillary's on board. A complete policy change in 48 hrs. — Laura Ingraham (@IngrahamAngle) April 7, 2017

Former Congressman Joe Walsh:

Syria isn't our problem. The Middle East isn't our problem. A tribal people cannot be bombed into becoming civilized.



Stop it Trump. — Joe Walsh (@WalshFreedom) April 7, 2017

French National Front leader Marine Le Pen:

#Trump is wrong about thinking of a military intervention in #Syria ... He would then follow the same path as those who intervened in #Iraq https://t.co/e6Uju54TFd — Marine in English (@Marine2017_EN) April 6, 2017

Columnist Katie Hopkins:

Former UKIP leader Nigel Farage:

Many Trump voters will be worried about this military intervention. Where will it end? — Nigel Farage (@Nigel_Farage) April 7, 2017

'Alt-Right' leader Richard Spencer:

Did Trump promise another war in the Middle East when he announced his candidacy? At the RNC? Inauguration address?



Total betrayal. — Richard 🦁 Spencer (@RichardBSpencer) April 7, 2017
