leverage

Trump's tariffs could provoke a global crash
through chronic drag, or counter-strokes acute.
Less Trade means everybody's got less cash,
like in the bad old days of Hawley-Smoot.
A hundred years of economic thought
--on tap if he would just consult the Fed--
could school him, if their counsel had been sought
but Trump takes counsel only in his head.
The WTO sits, it's poised to judge
what's indefensible, and what's just fair.
But Trump's in dudgeon, bent upon his grudge.
And peaceful resolution's a faint prayer.
Incurious of all that's gone before
Trump seems intent on launching a TradeWar.
