When the US and its allies suggested Ukraine's ability to strike Russia, President Putin responded with increased threats, including drills for tactical nuclear weapon use and reconsideration of nuclear doctrine. He also revived a defense pact with North Korea and warned of arming Kim Jong-un in response to Western support for Ukraine. These actions signal a new phase of escalation. Putin aims to pressure the West and prove his capability to antagonize beyond Ukraine. While some doubt his willingness to use nuclear weapons, concerns about potential escalation, including rogue arms transfers and cyber attacks, persist. This situation presents a precarious and complex challenge for global security.
