Ukrainian President Volodymyr Zelenskyy is looking on from the sidelines as NATO leaders meet to agree a significant boost in defense spending that is spurred by Russian aggression

Key US military commitments to Ukraine left over from the Biden administration are expected to run out within months, according to analysts, and there is uncertainty over whether President Donald Trump is willing to provide more.

NATO summit at The Hague is intended to signal to Russian President Vladimir Putin that the alliance remains united, despite US President Donald Trump's repeated criticisms and threats to pull out if defence spending targets aren't met.
