Wartime NATO summits have focused on Ukraine. With Trump, this one will be different

In Washington last year, the military alliance's weighty summit communique included a vow to supply long-term security assistance to Ukraine, and a commitment to back the country “on its irreversible path" to NATO membership. Then at the Group of Seven summit in Canada, Trump called for Russia to be allowed back into the group; a move that would rehabilitate Putin on the global stage. Also, some governments may struggle to convince their citizens of the need to boost defense spending at the expense of other budget demands without a strong show of support for Ukraine — and acknowledgement that Russia remains NATO’s biggest security threat.
