Of course all those bases have been built since 1979 when Iran decided to hold our embassy staff prisoner. . .History began before yesterday.
To be fair though you seem to be forgetting the entire TPAJAX Project in 1953 in which the United States CIA, along with the Brits, orchestrated the overthrow of the democratically elected PM Mosaddeq and gave all power over to the Shah. The Iranian people resented this to no end and it was probably the primary cause of the Islamic Revolution of 1979 in which Shah was also overthrown and the Ayatollahs were put into power. It is hard to be surprised at the reaction of the Iranians to our people in their country after we actively overturned their elected leaders and supported a man they saw as a tyrant for twenty years. I don't excuse the lunatics in Iran today, but at the same time, as you say, history began before yesterday.
Mossedeq tried to overthrow the constitutional monarchy and usurp power. And the Islamists didn’t like the socialists.
And no it really had nothing to do with the "Islamic Revolution" which was sponsored by the USSR. So sorry but you attempt to excuse the Iranian barbarity is noted and dismissed as the nonsense that it is.
And sure you excuse the Iranian lunatics of today, yesterday and everyday. After all they call the USA the Great Satan and Israel the Little Satan so they are to be loved, cosseted, made excuses for and defended.
It is really interesting how someone who "loves" their country never does anything but cut it down and side with it's enemies.
