Foreign conflicts in the 2020s are always like,

USA: Let's militarily encircle this large nation 

Large Nation: Hey stop 

USA: Let's heavily arm proxy forces right on their border 

Large Nation: We're drawing a red line 

USA: Let's cross the red line immediately 

Large Nation: *acts* 

USA: OMG COMPLETELY UNPROVOKED AGGRESSION
