The Crucial Role of Article 5 in NATO's Collective Defense

European leaders have had cause to rethink their roles within Nato recently, in light of statements coming from the US Government. The Trump administration’s dealings with Russia to try and broker a peace deal in Ukraine, have called into question America’s support for the alliance. But whilst the Trump administration say they are not pulling out of Nato and remain committed to the defence partnership with Europe, they have warned that they will "no longer tolerate an imbalanced relationship which encourages dependency". Nato currently asks member states to spend at least 2% on defence, but US President Donald Trump has consistently told European allies to spend much more than that target.
