Of course the American troops of Operation Urgent Fury were not invited by the sovereign country which they invaded.

Had the new government been a right-wing casino opening American friendly, trade union bashing government producing low-wage goods for the American economy you could have sent invitations from every country in the world and the Americans would not have invaded.

The Americans invaded a country of which the Queen was head of state, so did the Argentinians.

The Americans invaded a country without so much as a by-your leave - so did the Argentinians.

The difference was we didn't send a task force. So clearly there is no comparison.
