The American operation against the Houthis has political considerations (for example, sending a message to Iran), but also economic considerations, given the enormous damage that the Yemeni terrorists have caused to the global economy.
In January, The Economist estimated that "cargo shipments in the Red Sea are 70% lower" compared to the same period last year. The prestigious magazine estimated the damage caused by the Houthis to the global economy at about $175 billion per year.
The American operation is also intended to eliminate the "business model" created by the Houthis and allow them economic independence - blackmailing global shipping companies in exchange for not harming their ships.
According to estimates, the Houthis have brought in about $2 billion from this activity.
