Watch: Why is there a 'black cloud' over unity at the Nato summit?

At the Nato summit, tensions were palpable as US President Donald Trump openly criticized member countries for not providing sufficient support for his war on Iran, which has cast a shadow over unity among the alliance. Trump's unexpected comments about reviving his interest in taking over Greenland added to the discord. This situation underscores the broader challenges NATO faces in maintaining cohesion and mutual trust, especially when key member states diverge on critical global issues. For those keeping tabs on international relations, these developments highlight the complexities of global diplomacy and the importance of unified strategies.
