Depositing a $2 trillion dollar coin to reduce the nominal debt would itself have relatively little impact on the.value of the dollar, since it’s just in the essentially fake books of the US national government. Dollars, after all, are just coupons for “I am worth $1 towards any US government debt or court judgement.”
Depositing a $2 billion coin with the UN, in contrast, would have exactly the same inflationary pressure as giving 200,000,000 Americans 2000 $1 coins.

Except in the first US gulf war, back in the early 90s. (Kuwait was attacked by Iraq. The USA spent months preparing and then three days attacking. Then stopped when Iraq surrendered.)
Or the fall of the USSR. (Happened in about a month, no major fighting.)
Or the Russian annexation of Crimea.
It isn’t that short military exercises never yield results. It’s that wars persist until both attacker and defender believe peace is the best tactic.
The USA bombing a country for whom fighting the USA is essentially their national myth is possibly the dumbest thing that my country has ever done.
