Big Mistake
Trump says that Iran made a big mistake. In this video Trump strikes a conciliatory tone and offers the opinion that the incident may not have the support of the Iranian government but might be down to an over enthusiastic IRG (terrorist organization?) soldier. Trump adds that it is lucky that the drone was unmanned (aren’t they always?) so no loss of life.
It seems then that Trump is less inclined towards war than Pompeo or Bolton. Perhaps Trump remembers the promises he made to voters or perhaps he remembers his previous tweets?
Disputed Location
The location of the drone crash site has become clearer:

Ooops! Big Mistake. That is not the drone crash site but the site where the USS Vincennes shot down an Iranian passenger plane in 1988 (AR Flight 655) that was definitely “manned” (including 66 children). Bush senior publicly stated that America would not apologize and Bush gave the Medal of Honour to the captain of the Navy Vessel. Perhaps the Iranians should hand a medal to the drone shooter and blow a big raspberry at the US. The only one making Big Mistakes here is the US. Here is the crash (and launch) sites:

It is a big Mistake for Iran to continue its war mongering:

Banker Wars
Although the Yinon Plan for a greater Israel lies behind much of the trouble in the Middle East, the situation cannot be reduced to a single factor as multiple intersecting interests (including oil supply and the petro dollar) are driving the chaos. The old adage that “all wars are banker wars” holds true because many of the moneylenders have the same interests as the territorial expansionists – it seems they have hit a sweet spot that allows the simultaneous achievement of multiple goals namely, territorial expansion, oil security and petro dollar supremacy with the strategic goals of Israel merging with those of the US. It is not for nothing that many of the countries that rejected the petro dollar soon found themselves at war.

Update
It seems that everything was ready for early morning retaliation and Trump backed down. Trump must be under a lot of pressure from the war hawks. I wonder how he backed them down?
