Former Russian President Medvedev calls for preemptive strikes while Trump gives Putin a 50-day ultimatum to reach peace with Ukraine or face sanctions.

General Christopher Donahue, commander of U.S. Army Europe and Africa, said allies could seize Kaliningrad "in a timeframe that is unheard of."

President Donald Trump’s ultimatum to Russia to accept a peace deal in Ukraine within 50 days or face bruising sanctions has given the Kremlin extra time to pursue its summer offensive.

U.S. President Donald Trump's decision to ramp up arms shipments to Ukraine is a signal to Kyiv to abandon peace efforts, Russia said on Thursday, vowing it would not accept the "blackmail" of Washington's new sanctions ultimatum.

"Putin's criminal war is getting closer to our borders," Polish Foreign Minister, Radosław Sikorski, said on Wednesday.

The EU also targeted the Nord Stream pipelines between Russia and Germany to prevent Putin from generating any revenue from them in future, notably by discouraging would-be investors. Russian energy giant Rosneft’s refinery in India was hit as well.

Russia launched four missiles and 136 drones into Ukraine overnight into Monday morning, according to Ukraine's air force.

NATO members that border Russia are buying US-made HIMARS. One defense minister told BI that the war shows deep strike abilities are needed.

In a keynote speech in London last month, the NATO Secretary General Mark Rutte repeated a warning he has made in public at least three times this year: the western alliance is severely lagging behind Moscow on ammunition production.
