What should we fight for?
For while whose flag flies over Crimea has never been crucial to us, it is to Putin. And like Israelis, Russians are resolute when it comes to taking and holding what they see as rightly theirs.
Both these conflicts reveal underlying realities that help explain America's 21st-century long retreat. We face allies and antagonists who are more willing than are we to take risks, endure pain, persevere and fight to prevail.
This month, just days after North Korea tested a new ICBM, national security adviser H. R. McMaster declared that Trump "is committed to the total denuclearization of the Korean Peninsula."
If so, we are committed to a goal we almost surely are not going to achieve. For, short of a war that could go nuclear, Kim Jong Un is not going to yield to our demands.
For Kim, nuclear weapons are not an option.
He knows that Saddam Hussein, who had given up his WMD, was hanged after the Americans attacked. He knows the grisly fate of Moammar Gadhafi, after he invited the West into Libya to dismantle his nuclear program and disarm him of any WMD.
Kim knows that if he surrenders his nuclear weapons, he has nothing to deter the Americans should they choose to use their arsenal on his armed forces, his regime, and him.
North Korea may enter talks, but Kim will never surrender the missiles and nukes that guarantee his survival. Look for the Americans to find a way to accommodate him.
Consider, too, China's proclaimed ownership of the South China Sea and her building on reefs and rocks in that sea, of artificial islands that are becoming air, missile and naval bases.
Hawkish voices are being raised that this is intolerable and U.S. air and naval power must be used if necessary to force a rollback of China's annexation and militarization of the South China Sea.
