Some of us still resent the wa y they acted during the Falklands war...
Contrast the way our two allies reacted...the USA supplied the RAF with air to air rockets and other vital ordnance as well as political and moral support.
France supplied Argentina with a continuous supply of exocet missiles AND the French technicians to fit them cos the Argentinians couldn't have done it otherwise.
Who would you have backing you in a war.
Lets face it, when the going gets tough, the tough get going...but generally not as fast as some people and not necessarily in the same direction.as the BEF found out before Dunkirk.
