Secretary of State Anthony Blinken has recently warned members of Congress that Azerbaijan is on the cusp of launching an invasion of the last enclave of the historically embattled Armenian people. For historical context, the Armenians are a truly ancient race who once called all of Eastern Anatolia their homeland and settled as far as the Levant and the shores of the Mediterranean. But the passage of time has been less than kind to them. Today, all they have left is a tiny piece of real estate smaller than the state of Maryland.
Azerbaijan recently succeeded in the ethnic cleansing of some 120,000 Armenians from their homes in the Nagorno-Karabakh region. You'd think that would be enough for them. But the Azeris, cut from the same cloth as their more numerous Turkic cousins to the west, would like nothing better than to see the total subjugation and possible annihilation of the Christian Armenians. Buoyed by a higher population and awash in oil money, along with the final deterioration of Russia's role as a peacekeeper in the post-Soviet space, Azerbaijan has all the tools it needs to successfully invade.
Armenia is landlocked and it would be extremely difficult for even the United States to reinforce them military in the event that Azerbaijan attacks. But I am of the opinion that the US can and should deter an Azeri invasion, by way of lending them several nuclear weapons. It would be the most cost-effective way to guarantee peace in the Caucasus.
