I don't think that closing down the straits of Hormuz will be enough to bring countries such as the U.S. to war. When Japan threatened to close off the Malakka straits during WW2 nothing happened. It's only when the attack on Pearl Harbor happened that the U.S. went to war.
No, funds will be made available, but only when it is too late and by then nukes will already have destroyed a lot of major cities causing millions upon millions of deaths. When war does come, the war itself will be long and protracted. I reckon that a protacted nuclear war will cause perhaps ten times the number of casualties than the last world war. Not a pretty foresight.
