[30] On 17 November 2023, members of the platform participated in protests and demonstrations marking the 50th anniversary of the fall of the Regime of the Colonels, the right-wing dictatorship that ruled Greece from 1967 to 1974.

[37][38] Members of the WAP attended a demonstration in Krasnodon and met with the former secretary of the Communist Party of the Donetsk People's Republic, Boris Litvinov.

[49] Following the conference, the Platform announced its "Washington Declaration", which condemned the "NATO imperialist alliance", and called for the building of a "worldwide Axis of Resistance.

[51][52][53] The platform celebrated the 100th birthday of Amílcar Cabral,[54] and released its "Dakar Declaration", which called for a global "strengthened anti-imperialist front"[55][56] Marxist–Leninist critics, including the Communist Party of Greece (KKE), argue that WAP lacks a Leninist understanding of imperialism.

[59] Academic Vittorio Caliguri notes that shortly after the reviewed English translation of Ruy Mauro Marini's "The Dialectics of Dependency" was published, revitalized discussions on the nature of imperialism arose in Marxist circles around the same time as the creation of the WAP and dissolution of INITIATIVE.

The World Anti-Imperialist Platform and the Communist Party of Greece have both engaged with Marini’s work to support their respective views on the importance of international solidarity versus national sovereignty in the struggle against imperialism[60] Ivan Pinheiro, former General Secretary of the Brazilian Communist Party (PCB), criticized WAP as a well-funded effort to legitimize powers competing for world hegemony.

[67] The Communist Youth of Denmark (DKU) has criticized the WAP for "distorting Marxist–Leninist principles" and "aligning with opportunistic and imperialist forces" under the guise of "anti-imperialism".

They argue that this perspective oversimplifies global relations into two confronting camps and incorrectly equates contemporary Russian actions with the anti-fascist alliances of the Soviet Union during World War II.

[71] Academics Ford and Svensson have used the Platform as an example of how contemporary networks of social movements and parties can embody the principles of critical pedagogy and revolutionary imagination.

Specifically, they use the Platform to illustrate how collective organizing and mobilization in an internationalist context can inspire and sustain a radical imaginary necessary for revolutionary change.
