Hillary threat to obliterate Iran!

It's nothing to do with lessons learned from two wars... actually if there is a lesson to be learned from two world wars, it's to do with allowing a threat like Nazi Germany to increase its military might and occupy surrounding states, while at the time we were reducing our armed forces and the generals playing golf all day.

During the second world war, the world wasn’t prepared at all for the might of Nazi Germany, my father in the home guard aged 17 spent weeks testing crates of weapons sent over to us from the US, quite simply because our armed forces were so under equipped.

So there's your lesson, when there's a potential threat in the world then 'balance of power' is critical.

Clintons threat was right in that it sent a clear message to the dictator in Iran that any attack on it's allies would be met with equal retaliation. And it's that willingness to defend that prevents wars, not creates them. Wars occur because one side is vulnerable and weak and the other dominant with something to gain. Balance of power worked throughout the cold war, without it we may not have continued to exist.

The basis of Hilary’s comment was valid, however, it was her diplomacy that was lacking.
