Cameron gives full spectrum approach to combat terrorism

British Prime Minister David Cameron addressed the Commons on Tuesday to set out a "full spectrum" approach to deal with the terrorist threat from ISIL, also known as IS, especially to push for a vote on extending military strikes in Syria.

In his statement, the approach would include military action, counter-terrorism expertise, humanitarian support and strategies for defeating the "poisonous ideology of Islamist extremism."

He stressed "this murderous violence requires a strong security response," and "my firm conviction is that we need to act against ISIL in Syria."

He said Paris attacks had strengthened the case for air strikes, suggesting there could be a fresh vote on the issue.

On military power, he said now Britain's role is training local forces, striking targets in Iraq and providing vital intelligence support during cooperating with allies.

However, he said ISIL is not just present in Iraq, but operates across the border in Syria. "Raqqa is the head of the snake." When Britain is facing a direct and growing threat, "we need to deal with it, not just in Iraq, but in Syria too."

"Over Syria we are supporting our allies -- the U.S., France, Jordan and Gulf countries -- with intelligence, surveillance and refuelling," he added.

Cameron has promised a "comprehensive strategy" to win MP's backing for bombing IS militants in Syria as well as Iraq.

On counter-terrorism expertise, he said in next week's Strategic Defence and Security Review, "we will make a major additional investment in our world class intelligence agencies," which will include over 1,900 additional security and intelligence staff.

He also said at the G20 Summit in Turkey over the weekend all parts agreed on sharing intelligence and stopping threat of foreign fighters from travelling, and consented for the first time to work together to strengthen global aviation security.

On humanitarian support, he said last week Britain committed a further 275 million pounds to be spent in Turkey, a country hosting over 2 million refugees. And in next February Britain will seek to raise further significant new funding.

He believed it's crucial to understand and address the root causes of terrorist threat to defeat terrorism in the long run.

He proposed taking strategies including inspecting and shutting down any educational institutions that are teaching intolerance, encouraging reforming and moderate Muslim voices and backing those who "share our values." Endit
