The recently deceased Sir Nicholas Henderson was British Ambassador to Washington during the Falklands War, and allegedly “secured American support” for Britain during that conflict.
What “American support”?
The Reagan Administration was on the other side, just as NORAID literature from the same period makes it abundantly clear that the CIA was funding the IRA, ostensibly in order to take out the Workers’ Party but the money was rolling in.
No wonder that Thatcher signed the Anglo-Irish Agreement.
And no wonder that she issued what amounted to the open invitation to Argentina to invade the Falkland Islands, followed by the (starved) Royal Navy’s having to behave as if the hopelessly out-of-her-depth Prime Minister did not exist, a sort of coup without which those Islands would be Argentine to this day. Exactly as the Americans wanted them to be then, and want them to be now.
