Article 5 has:
such action as it deems necessary, including the use of armed force
which might also be thoughts and prayers while Trump is in the White House and
Any such armed attack and all measures taken as a result thereof shall immediately be reported to the Security Council. Such measures shall be terminated when the Security Council has taken the measures necessary to restore and maintain international peace and security
which is basically what was offered to Ukraine.
NATO requirements are also fully met if the US deems that doing nothing is the necessary action and informs the Security Council.
