I will only defend this land when there are things still worthy
of defence.If my family is safely ensconced overseas, my place will
be with them.Family before state is my belief.It all boils down to
what we are defending, a regime or a country.The lines are very
blurred these days.
Slam me if you wish.I have served my time and I have seen things
you might have not seen.
It seems your family is the only thing worthy of your defence
contribution. What about your colleagues, friends, relatives?
Forgetting about any sense of national identity or pride (the govt
is not equal to the nation), what about your assets here, assuming
you do have some assets in savings, CPF, property, etc? I'm sure
these count for something.
Do tell us about the things you have seen that might cause one to
be, shall we say, somewhat cynical.
