Yes, the current strategy seems to be to outspend them as we did with the Soviets but Iran will go down in a few short years vs. decades like the Soviets. Giant cracks on their economic windshield are accelerating like mad.
However, the madmen of Iran’s leadership is different then the Russians. Before their economy collapses, their is a high probability they would launch an offensive on Israel.
Such an attack would yield devastating consequences to their country but the strange mindset of the Middle East and overconfidence never seems to change hence the high probability of such occuring.
Of course, such an event would cause a drastic increase in oil prices and on top of the sub-prime disaster the financial impact to the US and global economy will be devastating.
