But even if they do have enough Air-lift capability,and
ships,their ships are mostly vintage warships,and since as an
island,RSAF should have enough time to react by downing the
aircrafts both combat and transport,the transport aircraft would
most probably be ferrying their Special Forces and air-dropping
them unless they are capable of doing what the Israelis did in
Operation Jonathan and land at one our air-bases or airport,which
is highly unlikely as they will be intercepted.After dealing with
the aircrafts,RSAF can simply give a hand to the RSN and take out
whatever ships they have sent our way.Indonesia is not a big
problem really,as we would have ample time to organise a defence
and and offensive operation.
But the bigger problem would be from Malaysia.From Johor,the
distance is only across a causeway,even if it was blown up,their
LSTs,or what can be over here in like 20mins.Thus,although it is
important that we build up our defenses on one area,we must not
forget that we are just an island with many "big brothers"around
us,some more offensive,the others less offensive.
Just my 2cents
