You seem complacent about the situation, to me at least.
First point - It is true, Malaysia will not invade Singapore unless
it is ready. However, military readiness is hard to judge at times.
By buying more arms, they are able to expand their orbat,
theoretically "more ready", but that for the most part, isn't the
case as we have discussed earlier. You can never tell when a
potential crisis may occur, and how quickly it may escalate.
Second point - The point is mostly economic, however i do get your
point on training people to new fields from a young age. Then again
it doesn't factor for much in this discussion.
Third point - It is generally understood that Malaysia may not
physically invade Singapore, however that does not mean their arms
purchases mean no threat to us. Any arms purchases in the region
has to be taken seriously. Also, we did not counter their arms
purchases by buying arms that directly counter their latest
aquisitions. Such an act amounts to an arms race. If you would look
carefully, you will find that we are the ones that do the "market
research" for them. We have more advanced equipment before them,
and thus it seems that they are the ones countering our
capabilities.
I don't really understand who the "we" in your post refers to, but
I'll talk on it both ways.
"We" - the forum. Well, this is a forum afterall, and for the sake
of discussion we have to bring up topics as far-ranging, yet
relevant as possible.
"We" - The general population and the Government. This is even
worse, the general population may not have much information as some
of us here, and they definitely view every purchase as a threat.
For the Government, like I've stated earlier, we cannot afford to
be complacent.
As for your last line, we did not oppose to their training nor try
to interrupt their arms purchases, we just kept quiet while they go
on blabbering on what they are looking at.
