America has choices as to how its empire dies. From William Schryver at imetatronink.substack.com:

Sic Transit Gloria Mundi
The inexorable decline of the American Empire has arrived at an Imperial Paradox. It must either fight a war and die, or not fight a war and die.
Here are the options:
China
Neither South Korea nor Japan want anything to do with a war against China, leaving only the Philippines dumb enough to play along.
The US apparently pulled another brigade out of South Korea. They’ll pull out more in the future. They know damn well the North Koreans could easily conquer the entire peninsula if they chose to do so.
China and its local seas are a vast ocean away from America, and its capacity to defend its local seas is enormous and growing.
The Pentagon must understand it cannot sustain logistics in a war against China in the western Pacific. It simply cannot be done. Anyone who thinks otherwise must upgrade their proficiency in basic arithmetic.
Iran
In the context of a war against Iran, all the geography is against the US.
Iran is an exceedingly mountainous country that has, over the course of millennia, learned to use those mountains to defend itself against would-be conquerors.
They can field a satisfactorily well-equipped million-man army.
They have learned in the 21st century to burrow deep heavily fortified tunnels into their mountains.
Iran is also much more technologically advanced than most people understand. They have become impressively capable in terms of both offensive and defensive missiles. They pose a far greater challenge than the Yemeni have been over the past year and a half.
Indeed, they pose a “near-peer” challenge against US overseas power projection.
North Korea had a problem with ship launch. (honk)
FUSA launched Minuteman III 4200 miles across Pacific.
Draft the replacements for the glorious world conquering tour.
