By the way, those negotiations have bought exactly nothing. They rented time. Americans take a greater interest in owning our peace of mind whenever possible.
Still don't understand this - the USA has been negotiating with Iran for decades, even helped start their nuclear capability (granted decades ago). Why has this suddenly become "our" fault?
By the way, why are you so certain that Europe bought time... and Iran didn't?
Because that is what USA and EU intelligence agencies and so on have been reporting i.e. that they'd stopped their development of nuclear capabilities.
I still do not follow your logic.
What has happened in the last few years is that countries like the USA, UK , France, Germany, Russia and so on have been involved in trying via negotiation to prevent Iran developing or obtaining nuclear weapons.
Iran obviously states it is still into trying to develop nuclear weapons but has now restarted research and construction plans that could lead to nuclear weapons or nuclear power.
Now you are apparently saying that the USA, UK, France, Germany and so on have wasted all this time.
Therefore I am assuming that you hold that military action should have been taken against Iran sometime in the past (presumably at least two years ago). At what date should this action have happened, how have you determined that (which can't be hindsight) and who should have undertaken this military action and why didn't they?
