Turkey has been at the risk of default for years, but it is not going to happen because it is normally trading with the world. Iran is isolated because we decided to free the Palestinians from Israel, an issue that is not in our top national priorities.
I knew the ISIS would be created against Iranian influence in the region a couple of years before it happened. I had read about it in a book by an ex-CIA operative who said one of the main goals of the US to contain Iran should be to invest on Sunni extremism to curb Iran's regional influence. It was a book by Robert Baer, published during Ahmadinejad's presidency.
That said, it all happened because we showed up on the US radar as a threat to their national interests. Nobody put us there except our own mistakes.
Iran was never an enemy by definition. Not until we decided to define our post-revolution identity as an anti-American, anti-Imperialist revolutionary country that is bound by oath to be against Israel. It was our choice to do so.
The US and China relations have had its ups and downs, but the Chinese never chanted Death to America and the Americans never sang Bomb Bomb Bomb China. Again, we identified our state post-1979 revolution as an anti-American, anti-Imperialist revolutionary state that wants to liberate the oppressed. We defined our own identity post-1979 revolution and the world believed it.
