This video from London, England says about itself:
25 September 2014
Anti-war campaigners gathered outside Downing Street to protest over the air strikes against Islamic State militants in northern Iraq and Syria. Members of the Stop the War coalition held placards and chanted slogans while U.S. planes continued to pound Islamic state positions in Syria. Prime Minister David Cameron said he wanted Britain to join U.S.-led air strikes against the Islamic State militant group after the Iraqi government requested London’s help and he recalled parliament to secure its approval for military action. Britain was quick to join military action in Afghanistan and Iraq a decade ago. But a war-weary public and parliament’s rejection last year of air strikes on Syrian government targets prompted Cameron to proceed cautiously this time and win cross-party support before acting.
Translated from the site of the Socialist Party (the biggest opposition party) in the Netherlands:
Everyone is eager to bomb ISIS. Why not so the SP?
With air strikes one cannot fight terrorism. The ISIS warriors just mingle among the people who will be the victims of the military campaign which now under the leadership of the United States has begun and about which they say that it will last for many years. In addition, the Sunni population will be driven by the air strikes into the arms of ISIS. …
What lessons can we learn from previous Western military interventions?
The main lesson to be learnt is that these interventions only very rarely ever lead to positive results and that Western military interventions often lead to an increase in violence. Afghanistan, Iraq and Libya show that. The violence in these countries is at an unprecedented level.
