As NATO allies make a show of unity in support of Ukraine, a rift between Germany and Poland risks undermining a joint effort to supply Kyiv¡¯s forces.

Quarreling in Warsaw and Berlin over missiles, tanks and spare parts has reached a new level, even as President Volodymyr Zelenskyy calls on western backers to ¡°hurry up¡± in delivering armaments before any spring offensive gets under way.

Polish leaders are now losing no opportunity to take aim at Berlin, a familiar target. Recently the accusations have focused on foot-dragging on sending battle tanks to the front ¡ª which triggered a threat to send German-made armor without Berlin¡¯s approval.
