What options are European leaders considering in their response to the Ukraine crisis?

At an emergency meeting in Paris, European leaders discussed various strategies to respond to the Ukraine crisis. These options range from dramatically increasing defense spending to reduce U.S. dependency, to providing direct security guarantees to Ukraine. Some leaders, including France and Britain, proposed sending troops to Ukraine, though Germany rejected this approach. This diversity of proposals highlights the significant challenge of forging consensus among European nations with differing security priorities. The fragmentation within Europe is evident as leaders struggle to develop a united response amid growing concerns about Russian aggression.
