As Politico reported, French President Emmanuel Macron has long urged Europeans to build their own defense industry through local procurement. “That’s why Paris will not join the initiative to buy U.S. weapons, French officials said. The French government is already struggling to increase its defense spending as it struggles to cut its budget and rein in a huge deficit,” Politico wrote.

Italy also does not want to join the initiative and is justifying its decision with reasons related to the state budget.

"Italy has practically no budgetary capacity for this. The purchase of US weapons for Ukraine has never been discussed here," sources from the Italian Defense Ministry told La Stampa.

Czech Prime Minister Petr Fiala also stated that his country would not buy weapons for Ukraine from the United States.

"The Czech Republic is focusing on other projects and ways to support Ukraine, such as the Czech Ammunition Initiative. Therefore, we are not currently considering the possibility of participating in this program," the prime minister told Publico.

According to media reports, the idea for the purchases essentially belongs to Germany. The German government believes that purchasing US weapons is one of the few ways to quickly provide Ukraine with the necessary weapons.

During a meeting with Donald Trump in the Oval Office, NATO Secretary-General Mark Rutte mentioned six NATO countries – Finland, Denmark, Sweden, Norway, the Netherlands and Canada – that have agreed to participate in the arms purchase program.

Poland's Foreign Minister Radoslaw Sikorski said Tuesday that Russia, not Europe, should pay for US weapons being sent to Ukraine. He made the suggestion at a meeting of EU foreign ministers in Brussels on Tuesday. Sikorski said he had asked his EU colleagues whether European taxpayers should pay for the equipment, adding that he believed it should be done from the aggressor's frozen assets.
