International cooperation during global crises is significant for several reasons. First, collaborative efforts enhance the effectiveness of responses to issues like pandemics or climate change, as these challenges transcend national borders. Shared resources, knowledge, and expertise can lead to quicker resolutions and more comprehensive strategies. Furthermore, international alliances can strengthen political and economic ties, fostering a sense of global solidarity. Finally, cooperation can pave the way for unified policies, enhancing stability and security in an interconnected world. Failure to cooperate, however, can result in fragmented responses and exacerbate crises.
