Answer:
The United States has betrayed the platform of the Anti-Imperalist League many times in recent history, by becoming an aggressor of foreign countries without enough justification.
Step-by-step explanation:
These aggressions can be seen in the American interventions in Iraq, Libya and Syria during the last two decades.
In the case of Iraq, the excuse was that Iraq held weapons of mass destruction, which was a lie.
As for Libya, the goal was the removal of dictator Muamar Gadafi from power, which the U.S. led coallition did in 2011, but 9 years later, Libya still lacks a stable government, and faces the Islamic threat of extremist groups.
Finally, in Syria, the U.S. Government also wanted to expel dictator Bashar Al Assad from power, but the war became a complicated matter, with many parties involved, and with Bashar Al Assad still in power. Nowadays, the U.S. in retreat, and Russia got the upperhand, so the intervention could be considered largely a failure in many ways.
