What are two examples of the successes and the failures in the past year in the u. s.?

In the past year, as always, the US managed to have some successes and some failures in its politics, economics, diplomacy.

Two successes are:

- mediating and sorting out the problem between Macedonia and Greece in the Balkans which is a region of big interest for the United States

- helping the domestic businesses and strengthening their position, resulting in an improved economy and an increase in the value of the dollar

Two failures are:

- the constantly increasing tensions with Iran because of bad diplomacy

- the fallen and unproductive negotiations with North Korea's leader Kim Jong Un
