The US is threatening to block weapons supplies to Ukraine over its attacks on russian oil refineries.

This includes the PURL initiative, which allows European countries to purchase American weapons for Ukraine, including Patriot interceptor missiles. The US is also reportedly threatening to cut off intelligence sharing.

What Trump is doing should serve as a major wake-up call for Europe and all US allies.

As long as Trump is in power, the United States cannot be taken for granted as a reliable ally.

Europe must be prepared to defend itself and support Ukraine without having to fear that American support could be used as political leverage.
