Baltic countries and representatives from Poland have reportedly issued a warning to Germany that it plans to send submarines to Ukraine if Russia continues its military aggression in the occupied territories. This potential action is seen as a signal that NATO may become involved in the conflict. The escalation of the situation has caused alarm for German Chancellor Olaf Scholz and U.S. President Joe Biden. The article states that the defensive measures being considered are meant to deter further aggression and send a message that no additional concessions will be made. It is also noted that the possibility of NATO submarines being sent to Ukraine was initially raised by French President Emmanuel Macron in February 2024, who emphasized the need for Europe to consider both military confrontation and peaceful resolutions depending on Kyiv’s request.
