1) Yes, but Malaysia and Indonesia is no Persia of our time, so branding ourselves as 21st century Sparta is a ridiculous analogy. In fact Malaysia is in such a sad state it has no real operating air force and relies heavily on trainer jets to make up the numbers. They also face a severe cash crunch and reports are coming out they are even prepared to procure trainer jets as an alternative for their future fighters.
2) No. Other than peripheral items such as light land weapons like rifles, ammunition and light armored vehicles, every major weapon system is procured from US / Europe. Without buying weapons from US / Europe, Singapore will be left with literally nothing else except infantry and light armour and perhaps a few small naval fast craft.
