Markets loved it.

Stocks, that is.

Bond traders were a bit more blasé, which is interesting because U.S.

treasuries, those government bonds and bills that basically the whole world owns at least a little bit of, are among the possible ways that Europe might fight back should the president's mood change.

Marketplace's Aubrey Beneshour gets us going.

Europeans own at least $8 trillion worth of U.S.

Treasuries.

Selling them off would make it harder and more expensive for the U.S.

to borrow money to fund all that spending.

There is, however, a problem.

Josh Lipsky at the Atlantic Council says European governments don't have a quick way of forcing private investors to sell their treasuries.

Then there's another minor issue.

It would not be in Europe's own economic interest to do something like this.

U.S.

treasuries back a lot of financial instruments around the world.

Any mass sale of treasuries like that would likely cause severe disruptions that would impact not just the U.S., it would also impact European banks and the entire global economy.

And on top of that, a lot of Europeans would lose a lot of money because it'd basically be a mega flash sale of U.S.

treasuries.
