As a Labour PM, Blair should have emulated predecessor Harold Wilson who, when asked to send squaddies to fight alongside the Americans in Vietnam, smartly said no.
Backing Ukraine is, of course, a noble cause but Vladimir Putin has made it clear that any deployment of peacekeepers would be regarded as Nato declaring war on Russia.
