You are entitled to your opinions and understanding. Believe or analyze it differently - no problem - Time is final judge of the future.
However to say that I'm looking the situation from the sectarian angle is your mistake and you are wrong. I don't needs to be in your good or bad books but that's only to set it clear for once.
Oil is the main cause of US presence in ME that's the basic fact. However war is not always an optimal solution to monopolize or protect interests. IMO, US attack on Iraq was not directly motivated by Oil interest. Saddam could have been equal servant to US in that respect. IMHO, that was a shoddy analysis by anti-war groups who were more scared to bring Israel and ME local politics into the mainstream politics. For many, Israel was the main cause among other domestic reasons, ideological mistakes and regional ME power dynamics.
To understand the current events in Iraq, one needs to read and comprehend the events through two US -Iraq wars and the prior Iran-Iraq war, including their military, ideological and political dynamics (I perhaps may claim that I know these events through the years and its actors with quite detail inside Iraq and US, but not any in Iran. Quite little information is available for internal Iranian political situation except for several foreign based commentators who are generally opposed to the Iranian regime - so those are not much help)
I standby my opinions in spite of your corny criticism. Further Trump's politics and intents are obvious but in US the position of president has only some weight - there are many other players who prevail. Yet there is a realization across the board that direct and fully paid war has not served well for US interests and power after cold-war era and some tinkling of the old policy and habits is needed - So one needs to see Trump presidency in that respect than for mindless criticism.
Again for the sectarian allegation, I may add that I don't support (sectarian) Islamic revolution in Iran or anywhere else or the obscurantist regime in saudia A number of my Iranian and Shia friends also had the similar position - (because similar political tilts bring us friends). However, allowing political position/ideology to taint the analysis or to mis-judge the facts on the ground is not an available option; better if you follow that course as well..
Your two claims are quite ridiculous. On one hand, you're so sure and on the other you make such ridiculous claims.
America will never attack Iran
Iran is no military threat to America or Israel
For the first claim, here's General Wesley claiming what we every Muslim knows will happen.
For your second claim, yes, Iran is no threat to America but it is to Israel.
I don't know how you pretend to be so expert but give such naive statements. I assumed it was because of sectarian hate but if you say, that's not it then i am baffled.
Iran will be attacked and it can be any number of ways. Either regime change, internal protests, coup detat, or conventional war. America will not stop until Iran is neutralised.
Iran has to be neutralised for Israel.
It would have happened long ago but things haven't been going according to Americans plan so it's delayed.
They just took out a country's top general (that's like Bajwa being droned) not through proxies but directly which is a clear criminal action and declaration of war and there are still people who think there's a nexus of America and Iran. America is simply testing the waters now.
The zionists lobby in America isn't a conspiracy theory, America is hostage to zionists, even Americans are realising this. Greater Israel project can't happen with a threat such as Iran.
