The West is lucky to have had such a leader during a key period of the Cold War:
A grocer's daughter with a steely resolve, she was loved and loathed in equal measure as she crushed the unions, privatized vast swathes of British industry, clashed with the European Union and fought a war to recover the Falkland Islands from Argentine invaders.
Argentinians may feel a little bolder with her passing.
UPDATE: More on Thatcher's legacy.
It is important to remember that late in the Cold War, many in the West assumed Soviet communism would win the Cold War. Some rejoiced in that fact while others simply regretfully accepted it as a fact to be coped with as best we could by delaying the inevitable as long as possible.
Yet once we won the Cold War, the left insisted that the fact that the USSR collapsed was proof that resisting the Soviet Union was a waste of money because the collapse of the USSR was inevitable.
And many still want to trust our left on foreign policy and defense matters. I don't get it.
Thatcher and Reagan rejected the inevitability of the West's defeat. That was their finest hour.
It would be nice if our leaders would embrace the superiority of the West over our Islamo-fascist enemies rather than seek excuses for why we deserve their murderous rage.
