Participatory Solidarity has vocally opposed the proposal to extend the operational range of South Korea's Cheonghae Unit to the Strait of Hormuz, characterizing it as an 'irregular deployment.' They are preparing to submit an emergency opinion statement to the government and the National Assembly to express their concerns. The group asserts that deploying the Cheonghae Unit to the Strait of Hormuz represents a fundamental shift in the purpose and nature of the unit's mission, which is primarily focused on anti-piracy and navigation support around the Aden Gulf and not on participating in foreign military campaigns.

The comments come amidst rising tensions as the United States has requested South Korea's involvement in naval operations in the region. Participatory Solidarity highlights past precedents, specifically referencing a 2020 situation when the Moon Jae-in administration expanded the operational scope of the Cheonghae Unit, amid requests for South Korea to join a maritime coalition following the assassination of an Iranian general. The group flags concerns over constitutional violations regarding the necessity of parliamentary approval for such shifts in deployment and the implications of intervening in a region experiencing conflict.

Moreover, Participatory Solidarity warns that deploying military forces to the Hormuz Strait, where conflicts involving U.S. and Israeli interests are ongoing, could implicate South Korea in acts of aggression that contradict international law. They argue that this expansion would not only exceed the mandate granted by the National Assembly but could also endanger South Korean nationals. The organization calls for a diplomatic and peaceful resolution rather than military involvement, urging the government to reconsider any plans to engage militarily in the region.
