War on Iran would certainly affect the price of oil and that, in turn, could function as the catalyst that would cause the rapid meltdown of the fraudulent US dollar, and culminate with USA losing its dominant position as the ruling state in the world. In a surprise of all surprises, Israel could then replace USA as the new ruling state in the world, while controlling the new electronic money-system of the world that would then totally replace paper-money.
It's natural to assume that the 'US dollar' is a United States thing, but I've some questions about this. Technically the USD is controlled (aka, 'owned') by the Federal Reserve which is a private entity. This entity was started with significant impulse from the Rothschild banking house who presumably took at least a large stake in it, and there seems little reason to believe that they ever liquidated their share over the last century. An 'Audit the Fed' program could shed some light on this...which helps explain why it will never happen.
As for Israel, the same Rothschild banking house was key to setting up Israel, and a simple read of history makes it pretty clear that Israel was 'their baby.' Going all the way back to WW-I the Balfour Declaration was addressed to Lord Rothschild and outlined the desire to have 'Palestine' be a 'homeland for the Jews.' A fallout of WW-I was the fall of the Ottoman empire and thus freeing up of Palestine. The fallout from WW-II saw the formation of the Jewish state of Israel.
Between the above two observations and the 'world reserve currency' status, I think it is fair to ponder whether the the USD is not as much an 'Israeli thing' as it is an 'American thing' at this point.
I, as an American, have no particular beef with the Persians. On the other hand, those who have loyalties to the Jewish state of Israel cause what I perceive to be all kinds of grief in my country. If Iran is operational in Syria it is by invite from the legitimate leader of Syria. Israel has hundreds of nuclear weapons and has a history of using the threat of nuclear attack to 'win wars' by the looks of things. Iran has been on the receiving end of several decades of blatant threats by Israel. The only logical defensive strategy when threatened by a nuclear armed belligerent is to disperse forces that they can pose a threat to the attacker even if one's country is turned into glass.
'We' in America current enjoy the benefits of the USD being world reserve. Or do we? The benefit is not felt very equally. What good is it to be made rich and strong if the strength is going to be tapped to fight foreign wars which do most people no good at all, and especially if the country itself is running deficits and going into significant debt. For my part, I'm feeling that it's about time to default and switch to a new monetary system. More and more people are seeing the scam of using someone elses' debt-backed monetary system. It's well documented on enough people's thumb drives so there is a pretty good chance that we'll avoid making the same mistake twice when a replacement is formed. Even if we are not ideally ready in this respect, I'm willing to take a chance if we could possibly make the switch before being herded into WW-III.
From an individual perspective, I very much like to show my support with my wallet. Since 2011, the promise of crypto-currencies has been, to me, that it becomes practical to do so. I, as an individual, would like to be able to choose to support Persia and not support the Rothschild banking house and their minions. I would like to be able to perform transactions with the benefit of whatever transaction fees I pay accruing to Iran. Or at least to any entity who is giving me the best deal.
Crypto-currencies have always been primarily a political thing to me, and a hopeful replacement for guns and bombs. If they don't come in time to avoid the next great engineered depopulation event, I can only hope that they are used to their potential in the rebuilding that comes after.
