German Chancellor Olaf Scholz, Prime Ministers of Denmark Mette Frederiksen, Czech Republic Petr Fiala, Estonia Kaja Kallas and the Netherlands Mark Rutte in a joint letter called for collective efforts to arm Ukraine in the long term.

The letter was published by the Financial Times. "We call on friends and partners of Ukraine to recommit to sustainable long-term military support for Ukraine as a joint European responsibility. This decision must be taken by each and every country. Only then will Ukraine be able to succeed in its defence against Russian aggression," according to the letter.

Leaders call on EU member states to step up military support for Ukraine and do everything possible to do so – this must remain a collective effort. It is also emphasized that "Russia doesn't wait for anybody and we need to act now."

"If Ukraine loses, the long-term consequences and costs will be much higher for all of us. We Europeans have a special responsibility. Therefore, we must act. Europe’s future depends on it," the leaders said.

It is stated that "our ability to continue to support and sustain Ukraine’s defence, both during the winter and in the longer term, is decisive. In fact, it is a matter of our common European security, and for the brave women and men of the Ukrainian armed forces a question of life and death," the leaders said in the letter.

According to the letter, it is now extremely important to provide ammunition and weapons systems, including howitzers, tanks, UAVs and air defense systems, which Ukraine so desperately needs.

"We must therefore insist on finding ways to accelerate the delivery of the promised artillery rounds to Ukraine," the leaders said in the letter.
