I fully agree with Mr. Tng. If the whole PAP cabinet resigned
today, or died in a plane crash accident, killed in an accident
with a beer truck, or poisoned by terrorists in a party, there will
be citizens of singapore who would be prepared to come forward to
manage the country. Our share market would be down for a few days,
but it will recover. The SAF would be ready to repel any enemy
trying to take advantage. Our ports will continue receive vessels
and tourists. Business would be as usual, lives go on as normal. It
may take a month of transition before a general election can be
held, but it will not take longer than the military in Thailand.
Those who love Singapore will stay and hold the nation together,
those who have wanted to migrate would migrate anyway, how fast
they go does not depend on them or Singapore, it depends on the
countries that are prepared to accept them, as usual.
We may not have any growth for one year, but singapore economy will
not collapse. We may not achieved no. 1 in many areas, but
Singapore will remain a sovereign nation, more than just surviving.
I am certain Singapore is resilient as such.
What comes next? Will the new government performs better than the
PAP government, with lesser evil, or will there be more evil and
lesser achievement? would we later need a new generation LKY, and
then history repeat itself? The hard fact in life is that we
usually don't have a second chance. It is not easy.
