Russian President Vladimir Putin, on Tuesday, delivered three strong signals that he intends to invade Ukraine.

Addressing military commanders and intelligence chiefs at the Defense Ministry, Putin offered a preemptive casus belli to justify invading Ukraine in order to address an existential threat to Russia. The Russian leader warned that the United States “will supply Ukraine with hypersonic weapons,” which would reduce the nuclear strike launch-to-target time against Moscow to “five minutes.” This, Putin insisted, would pose “the most serious threat” to Russia’s security. One that means “we simply have nowhere to retreat further.”
