National unity is not a slogan. It is a strategic asset. In a moment of crisis with Thailand, Cambodia’s strongest non-military advantage is legitimacy, meaning how credible Cambodia appears to its own citizens and to the outside world. Unity among Cambodian political forces will not immediately stop Thai military pressure, but it can strengthen Cambodia’s position in regional and international diplomacy, narrow the space for hostile pretexts, and expand support for lawful and peaceful solutions.
When Cambodia seeks backing from ASEAN, major partners, and international institutions, those actors do not evaluate Cambodia’s legal claims alone. They also judge whether Cambodia speaks with national consent or mainly with the voice of a narrow governing circle. In contemporary geopolitics, legitimacy functions as strategic power, especially for smaller states facing pressure from stronger neighbors. If Cambodia demonstrates genuine internal cohesion, it becomes harder for an aggressor to portray the dispute as a purely internal political problem, to question Cambodia’s credibility, or to justify pressure through manufactured narratives.
For that reason, real national unity must begin at home, and it must begin with the political will of Hun Sen and Hun Manet. Cambodia cannot convincingly ask the world to defend its sovereignty while major parts of its society remain politically excluded, politically punished, or silenced. If the ruling party wants a unified national front, it must take immediate steps that broaden participation, rebuild trust, and increase Cambodia’s diplomatic leverage.
The first step is restoring political legitimacy through meaningful political openness. Cambodia’s international democratic credibility suffered serious damage after the dissolution of the Cambodia National Rescue Party in 2017 and the subsequent tightening of civic and political freedoms. This history shapes how foreign governments and international institutions interpret Cambodia’s appeals today. Rebuilding legitimacy does not require a perfect democracy overnight, but it does require credible signals that competition and participation are real. Reopening political space, protecting civil society, and ensuring the opposition can operate without intimidation are central to that credibility. Whether through reinstating the CNRP or ensuring that opposition forces can compete freely, the logic is the same. National unity cannot be genuine if a large share of the electorate is structurally excluded. A more open system strengthens Cambodia’s diplomatic standing because international support often depends on governance credibility, rule of law, and respect for rights.
The second step is turning national reconciliation into visible action by resolving high profile political prisoner cases, especially Kem Sokha and others detained for political reasons. This is not only a humanitarian matter. It is also a strategic test of whether the government’s unity narrative is sincere. Releasing political detainees and ending politically driven restrictions would reduce polarization at home, rebuild public confidence, and improve Cambodia’s international image precisely when Cambodia needs wider support. If unity is meant to function as a national shield, reconciliation among political actors becomes part of national security rather than an optional gesture. A government that can demonstrate internal reconciliation is better positioned to lead a credible diplomatic campaign against external aggression.
The third step is removing governance vulnerabilities that weaken Cambodia’s credibility and provide space for hostile pretexts. Issues such as online scam operations, human trafficking networks, and illicit businesses protected by impunity have damaged Cambodia’s reputation and reduced confidence in state institutions. In a crisis, an opponent can exploit these weaknesses to shift attention away from aggression and toward claims of security operations or cross border crime narratives. Cambodia can reduce this risk by acting decisively through transparent prosecutions, independent oversight, and cooperation with credible regional and international investigative bodies. This is not about satisfying outsiders. It is about denying an aggressor a ready made excuse and reinforcing Cambodia’s claim that it seeks lawful solutions.
These three steps form one coherent strategy. Political openness builds legitimacy. Releasing political detainees demonstrates reconciliation and seriousness. Cleaning up impunity driven illicit networks strengthens state credibility and reduces exploitable vulnerabilities. Together, they expand Cambodia’s diplomatic options. Cambodia can more persuasively call for ASEAN engagement, international observers, impartial investigations, and internationally recognized ceasefire or de-escalation frameworks. They also make it easier for other states to take clearer positions and condemn violations of Cambodia’s sovereignty without fearing they are endorsing domestic repression or overlooking governance failures.
National unity also matters in the information domain. Border crises are often fought through narratives as much as through physical pressure. A pluralistic political environment encourages diverse and credible information sources, which helps external audiences distinguish legitimate sovereignty defense from incitement, disinformation, or hate speech. That credibility supports diplomacy because international partners respond not only to events but also to the trustworthiness of the information they receive.
The alternative is predictable and costly. If calls for “National Unity” remain rhetorical while opposition forces remain excluded, political restrictions persist, activists face harassment, and impunity driven illicit economies continue, Cambodia’s legitimacy gap will remain. That gap will limit Cambodia’s ability to mobilize regional and international support and will give Thailand more room to weaponize Cambodia’s domestic weaknesses as moral or political cover for coercion. At a time when the rules based international order is already strained, a country with weakened legitimacy faces a higher burden to persuade others to act decisively. Therefore, Cambodia’s strongest long-term defense strategy is not only military readiness or diplomatic outreach. It is removing internal weaknesses that erode legitimacy and building a genuine national consensus. If the ruling party truly seeks unity as one Khmer, it must begin with internal political concessions grounded in democratic principles and a real commitment to rule of law. Otherwise, national unity will remain a repeated political slogan that may protect power at home but will be too weak to defend sovereignty abroad.
