An unexpected war our country should participate in

‌
I believe it is the Myanmar civil war.
Our country is no longer a developing nation, but one of the two leading advanced nations in East Asia, alongside Japan.
Therefore, we should not limit ourselves to defending the Korean Peninsula; if we think a bit more grandly, I believe we should become a nation that oversees the entirety of East Asia (including Southeast Asia).
This would be similar to how the United States acted as the world's policeman, or how the United Kingdom acted as the policeman of Europe.
Just as the UK has historically participated in wars occurring on the European continent, I believe we should also participate in wars occurring in East Asia by forming a Korea-Japan allied force.
Furthermore, China is expanding across all of East Asia.
They are building docking facilities around reefs in the South China Sea and controlling the surrounding areas with unmanned surface vessels and drones.
They are also threatening Taiwan and indirectly turning countries like Laos and Cambodia in Southeast Asia into satellite states by supporting dictatorial regimes.
In the case of Myanmar, China is behind the military regime.
Therefore, East Asian nations, excluding China, must unite to halt China's expansion.
This proxy war is exactly what the Myanmar civil war is.
Thus, I believe a Korea-Japan allied force should fight alongside Myanmar's democratic forces against the government troops.
Of course, rather than deploying ground troops, there is a need to gain practical combat experience through drone warfare.
