• It does force leaders to come to the table with the US.
• A handful of concessions can be extracted.
• Method of 'negotiation' is popular with base due to step 4.

Negatives:

• The concessions or wins are minor compared to short term damage done
• The longer-term position after concessions may be unchanged or worse than the starting position for the US.
• Immeasurable amounts of trust in the US is lost, foreign leaders look elsewhere to negotiate and strike trade deals rather than be bullied
• Foreign citizen sentiment of US lowered, affecting US businesses and political influence on the world.
