Despite concerns that Europe could be drawn into a larger conflict, the governments of the United Kingdom, Belgium and Denmark acted Friday to contribute to the fight against Islamic State militants in Syria and Iraq.

British lawmakers voted 524-43, and Belgium voted 114-2, to commit warplanes and other support to the U.S.-led coalition.

“This is about psychopathic terrorists that are trying to kill us and we do have to realize that, whether we like it or not, they have already declared war on us,” said British Prime Minister David Cameron. “There isn’t a `walk on by’ option. There isn’t an option of just hoping this will go away.”

Danish Prime Minister Helle Thorning-Schmidt said her government would send four operational planes and three reserve jets along with 250 pilots and support staff, reported the Associated Press.

“No one should be ducking in this case,” she said. “Everyone should contribute.”
