The world being so interconnected, any conflict in any part of the world has massive repercussion.
The most ominous threats in 2018 — nuclear war on the Korean Peninsula and a spiraling confrontation pitting the United States and its allies against Iran — could both be aggravated by Trump’s actions, inactions, and idiosyncrasies. U.S. demands (in the North Korean case, denuclearization; in Iran’s, unilateral renegotiation of the nuclear deal or Tehran’s regional retreat) are unrealistic without serious diplomatic engagement or reciprocal concessions. In the former, Washington could face the prospect of provoking a nuclear war in order to avoid one, and in the latter, there is the possibility of jeopardizing a nuclear deal that is succeeding for the sake of a confrontation with Iran that almost certainly will not.
