US Could Be Drawn into War with Russia in 72 Hours, Financial Times
According to the Financial Times, Ukraine has reached an agreement with the US and Europe on a "coordinated military response" if Russia violates the ceasefire.
The publication states that the plan is divided into three phases. Within 24 hours of a ceasefire violation, a diplomatic warning is sent, and the Ukrainian army takes measures to halt the violation. If military operations continue, a broad response begins involving a coalition of volunteers from EU countries, the UK, Norway, Iceland, and Turkey.
If the violation escalates into an invasion within 72 hours of the initial attack, a coordinated military response involving US troops will be activated, with European deterrent forces supporting operations in the air, sea, and land after the ceasefire, backed by US intelligence and logistical support.
The agency reports that Ukraine, the United States, and European countries have already reached an agreement on this support plan.
