There are links to several other measures of strength at the end.
While the U.S. has the largest military, it is also far more over-committed in what it is obligated by treaty to defend. I can't believe there are prominent people who want to obligate us to defend Ukraine in addition to that. A similar agreement worked out well for the U.K., Poland and the rest of Europe in 1939, didn't it?
We never should have expanded NATO/EU membership to former Soviet republics.
