If the US only conducts air/missile/drone strikes from afar and/or support proxies on the ground without using their own military then this will resolve to NO. It only resolves YES if US United States Armed Forces combat arms are on the ground. CIA saboteurs or agitators don't count. It has to unambiguously be US military.

If the US does not clearly attack in 2025 this resolves N/A regardless of whether there are US troops on Venezuelan territory or not

If the linked market below resolves Yes then for the purposes of my market the US has attacked Venezuela and my market can no longer resolve N/A:
