I remember during the Chirac presidency how viciously France was attacked by the other European countries, especially my own Sweden, for doing nuclear weapons testing in the South Pacific.
Jump forward today and France is seen as a protector of Europe, especially in Sweden, because of its nuclear arsenal.
That was not the most glorious moment of Chirac's presidency, no..
However, as someone involved in numerical simulations, the argument that it was needed to calibrate their numerical models does hold (some..) water..
But Chirac did partly redeem himself by refusing to invade Iraq on bogus US claims of WMDs..
Let's also not forget the absolutely absurd intervention of Colin Powell at the UN Security Council, holding up a vial containing the ultimate "proof" of WMD.
Good thing he didn't drop it.. /s
