Let's put the shoe on the other foot and think Iranian style - a proud nation that's been around for 2500 years.
In 1953 Iran was a parliamentary democracy and voted to nationalize some of its oil revenues for domestic development. The oil fields were run by British and American companies vehemently opposed to the idea. The CIA initiated a coup that put the Shah in power- a brutal regime dominated by a secret police that executed tens of thousands.
Forward to 1980-1988 when the U.S. financed Iraq in its war against Iran. One million Iranians died. Forward to 2003-2015 when Iran had invading American armies on its borders with both Iraq and Afghanistan. All the while, Iran is surrounded by India, Pakistan, Russia, Israel, and the U.S. Sixth Fleet, all armed to the teeth with nuclear bombs.
Can anyone truly blame Iran for trying to produce one measly nuclear bomb to defend itself from nuclear Armageddon? How would the US react if it had hostile armies on its borders with Mexico and Canada?
My advice to anyone who blames Iran for being a 'terrorist state' is to read up on the history and the hostilities of the last 70 years.
My take is that much of the chaos in the Middle East is still the aftermath of colonialism and the arbitrary borders that created 'nations' like Iraq and Syria where once only tribes roamed.
