National Review:

George Will is a Pulitzer Prize–winning syndicated columnist. 

Difficulties with Iran will recur regularly, like the oscillations of a sine wave, and the recent crisis — if such it was, or is — illustrates persistent U.S. intellectual and institutional failures, starting with this: The Trump administration’s assumption, and that of many in Congress, is that if the president wants to wage war against a nation almost the size of Mexico (and almost four times larger than Iraq) and with 83 million people (more than double that of Iraq), there is no constitutional hindrance to him acting unilaterally.

In April, Secretary of State Mike Pompeo was pressed in a Senate hearing to pledge that the administration would not regard the 2001 authorization for the use of military force against al-Qaeda and other non-state actors responsible for 9/11 as authorization, 18 years later, for war against Iran. Pompeo laconically said he would “prefer to just leave that to lawyers.” Many conservatives who preen as “originalists” when construing all the Constitution’s provisions other than the one pertaining to war powers are unimpressed by the Framers’ intention that Congress should be involved in initiating military force in situations other than repelling sudden attacks.

The Economist, which is measured in its judgments and sympathetic to America, tartly referred to the supposed evidence of Iran’s intentions to attack U.S. forces, allies, or “interests” as “suspiciously unspecific.” Such skepticism, foreign and domestic, reflects 16-year-old memories of certitudes about Iraq’s weapons of mass destruction: Remember Secretary of State Colin Powell spending days at the CIA receiving assurances about the evidence. There also are concerns about the impetuosity of a commander in chief who vows that military conflict would mean “the official end” of Iran, whatever that means.

U.S. policy makes easing economic sanctions against Iran contingent on Iran doing twelve things, most of which (e.g., halting development of ballistic missiles, withdrawing from Syria, ending support for allied groups) it almost certainly will not do. This U.S. policy is congruent with U.S. disregard of this truth: Any nation, however prostrate, poor, or ramshackle, that ardently wants nuclear weapons can acquire them. Just four years after Hiroshima, the Soviet Union, which had been laid to waste by World War II, became a nuclear power. China was an impoverished peasant society in 1964 when it detonated a nuclear weapon. Pakistan’s per capita income was $470 in 1998 when it joined the nuclear club. In the more than a decade since North Korea acquired nuclear weapons, U.S. policy has pronounced this “unacceptable.” But U.S. behavior has been to accept it while unfurling the tattered flag of arms control — hoping to talk North Korea into giving up what it has devoted three decades to developing.
