They have learned well from their Master LKY.
When PAP or LKY loses in any argument, out comes ISD to capture and threaten the enemies.
They also have no balls to come on a one to one fight in election, so they come out with GRC and 5 PAP candidates against 5 opposition candidates.
Since the government have no balls, so the Singaporean ah bengs also have no balls in a one to one fight too.
