King Tiger, it's not wrong to visit overseas historial sites.. But we have our own historial sites that we need to know and recognised with. There are some laying around in our estate...
Such as..
a) Chinatown - sook ching centre
b) Bunker structure in fort canning
c) Bunker boxes along Pasir Panjang
d) Fort factory - though it is a small place but it has many real historial items inside.......
e) changi chapel
f) Kranji War memorial
The hollywood movies tends to glorified the war and the story is almost one sided most of the times. Except the I heard the Iwo Jima is kinda of reversal...
Some of the sites that you can start with.. if only you're interested.
