"It is important that EU-level action be complementary to NATO action. It is very important that all these actions, in which we are involved at the EU level, are consistent with the actions of the North Atlantic Alliance," Duda told a press conference.
The statement was made after in November French President Emmanuel Macron said that the European Union should have a "real European army," independent of the United States, to be able to defend itself. German Chancellor Angela Merkel has supported the idea, suggesting that this joint force could be a complement to NATO, while US President Donald Trump has criticized it.
Recently, NATO Secretary General Jens Stoltenberg said that the European Union’s defence strategy should not compete with NATO.
