For "Yes" resolution:

Verifiable evidence of military strikes by Russia on NATO member countries hosting transit bases for Ukrainian military equipment or aircraft (like F16). Confirmation from credible sources such as government officials, international organizations, or reputable media outlets. Consensus among geopolitical analysts and experts acknowledging the occurrence of such strikes.

For "No" resolution:

Absence of verifiable evidence of military strikes by Russia on NATO member countries hosting Ukrainian transit bases.

Official statements or declarations from relevant governments denying any such attacks.

Reports from independent monitors or international observers confirming the absence of such strikes.

For "N/A" resolution:

In the absence of verifiable information (or false flag attacks), the bet would be resolved as "N/A" due to insufficient evidence to determine either "Yes" or "No" outcomes.
