SIR - The tragedy we are seeing in Yemen effectively involves only of one other nation, Saudi Arabia, to back the Yemen government forces.

The Houthi Rebels have been at war with the government there since the so-called Arab Spring. The US and UK among other allies have left the Saudis to their own devices in dealing with this long uprising.

This has resulted in appalling casualties among thousands of civilians as bombings and air strikes have been miss-targeted. It raises the question - why are other allied forces not actively helping in Yemen?

The Iraq War of 2003 happened partly because the UN was too impotent in dealing with Saddam Hussein, causing a vacuum of responsibility which the US and UK filled after 9/11. We have since seen a non-interventionist approach to foreign policy in the west resulting in not helping when we should.

This is because the Stop the War Coalition and related campaigns have achieved their aim, discouraging all foreign intervention, whether humanitarian or military. They have failed to acknowledge the good that intervention can do and has done effectively stopping it all. They've thrown the baby out with the bath water and we are now seeing the consequences.
