See if you can follow this logic: Vladimir Putin says he has developed a new breed of shield-penetrating intercontinental ballistic missiles as a countermeasure against the establishment of U.S. bases in Poland, Bulgaria, Romania and a radar systems site in the Czech Republic, designed to protect against aggression from Iran or North Korea.
Mr Putin said it was a "response to maintain the strategic balance in the world", in what he called a "new round of the arms race".
The equivalent response from the U.S. would be to boast that it has just developed a new series of Patriot missiles that can be launched from domestic shores and reach Moscow in record time.
