Absolutely.
As a tidbit, that's what Kohl (then German chancellor) said. He was not opposed at all but except under those conditions.
The trouble was heavy opposition to German unification, especially by Thatcher and Mitterand. So Mitterand used the opportunity to twist the German arm, i.e. by neutralizing its new potential in robbing it of the DeutschMark and forcing it to accept the Euro. To sort of curbing any control potential it might develop. Otherwise no re-unification. Kohl crumbled.
BIG BIG mistake (Mitterand's and Thatcher's, not Kohl's). The Euro has done Germany more proud than the DM ever did or could and is actually "harder" still today. And we know how much France is actually controlling Germany, right?
Won't mention the UK here
One more OT and then I'm done: Kohl didn't want Italy in it either (Spain and Portugal were not even in the offing then) but Mitterand insisted they come on board. As another counter-balance in case Germany got in bed with the (I'll mention them after all) Brits and joined into their pesky shenanigans.:mrgreen:
Big success, eh?
