Coin World reported that U.S. President Trump stated on the 25th local time that the details of how the U.S. will participate in the security assurance for Ukraine have not yet been discussed, but the U.S. will assist Europe in playing a major role in the form of 'support'. Trump made the remarks during a media interview at the White House that day. He said that the conflict between Russia and Ukraine is the 'easiest' among the multiple conflicts he intends to resolve. The Russia-Ukraine conflict involves some 'serious personality conflicts', but the U.S. 'will bring this situation to an end'. Trump also mentioned that after a series of meetings among U.S., Ukrainian, and European leaders at the White House last week, he had a phone call with Russian President Putin, and both hope to promote 'denuclearization'. When they met in Alaska, they also discussed the topic of reducing the U.S. and Russian nuclear arsenals after the Russia-Ukraine conflict ends.
