What role can the US play in deterring further aggression in the Ukraine conflict?

According to North American Editor Sarah Smith, the US can provide critical deterrence to Putin that would prevent him from launching further attacks. This deterrence capability is positioned as essential in maintaining regional stability and containing Russian aggression in Ukraine. The analysis suggests that without strong US involvement and commitment to deterrence, Putin may feel emboldened to continue or escalate military actions. This perspective underscores the significant role that American foreign policy and military posture plays in the geopolitical dynamics of the Ukraine conflict.
