If these military idiots don't go into politics under PAP, they have nowhere else to go. They won't enjoy the same kind of compensation if they go to the private sector. They lose face as they would have to start at a lower position in the private sector.
Going into the politics is not of choice. If they lose, they may get a consolation prize, like a job in PA or NTUC to wait for another shot, assuming the PAP is returned to power.
Time to end the career of these military idiots by disposing the PAP.
