International markets and geopolitical analysts are closely monitoring a significant escalation in the Russia-Ukraine conflict following the reported use of Western-supplied long-range missiles against targets inside Russian territory. The Kremlin responded to the developments by formally lowering its threshold for the use of nuclear weapons, a move that has drawn widespread condemnation from NATO members and European leaders. While Ukrainian officials argue that deep-strike capabilities are necessary to disrupt Russian military logistics, some international observers warn of a potential widening of the conflict. Amid the rising tensions, diplomatic efforts continue at the G20 summit in Brazil, where several nations have renewed calls for a peaceful resolution. Financial markets showed signs of volatility early Wednesday as investors weighed the risks of further instability against the backdrop of shifting global defense policies.
