The Wall Street Journal reports that Russia is preparing for a sustained and intensified summer offensive against Ukraine, involving increased ground operations and missile strikes across the country. This escalation comes amid a halt in U.S. military aid to Ukraine, including the suspension of air defense support. Approximately 50,000 Russian troops are reportedly involved in the planned operations. The Kremlin's decision to intensify attacks is linked to perceptions that the United States, under former President Donald Trump's administration, may abandon Ukraine, thereby influencing Moscow's strategic calculations. Recent explosions have been reported in Ukrainian cities such as Dnipro and Krivoy Rog. A recent phone call between Russian President Vladimir Putin and Donald Trump underscored Putin's determination to continue the offensive.
