Ukraine escalates conflict with first strike into Russia using U.S. missiles

The conflict in Eastern Europe has escalated significantly, with Ukraine recently launching its first strike into Russia using U.S.-supplied long-range missiles. This marks a shift from a regional conflict to a potential global crisis, as tensions rise. North Korea has sent 10,000 troops to support Russia, while the U.S. has authorized Ukraine to use ATACMS missiles against Russian targets. Russia has responded with threats of nuclear retaliation, indicating a serious increase in hostilities. The situation has drawn in more countries, raising fears of a broader war. Russia's new nuclear doctrine suggests any attack on it, supported by a nuclear power, will be treated as a joint attack, heightening the stakes for all involved.
