President Donald Trump is, as they say, transactional by nature, not an ideologue. His philosophy is to exert leverage by every means necessary and secure results that magnify his power and prestige. This is how he conquered the Republican Party, won the presidency twice, brokered the Abraham Accords and the U.S.-Mexico-Canada Agreement, and more. 

But scattered among these victories of leverage application are numerous failures, instances in which he pulled the bow too tight, only to have it snap in his hands rather than deliver a bullseye. And these, too, must be factored into any honest accounting of his deal-making record.
