lets look at some of the countries with conscription systems. we don't have to be military-trained or possess some brilliant IQ and foresight to analyse the necessity of National Service.
1) South Korea
constantly under threat of a nuclear-equipped North and stuck in the 6 party-relationship. their real peace will only come when Korea is unified. besides the North, they also have uncertain relationships with...
-China
stability of China depends on one Premier, who is the next communist after Wen Jia Bao we don't know, yes don't ever forget the fact they are still COMMUNISTS)
-Japan
the WW2 hatred will always be there, whoever the government is.
-US
growing pressure from US citizens to keep their hands off the other countries' affairs, again this depends on US voters. majority is the tyranny of democracy, never mind others' death and stabilitythus, National Service Conscription for South Korea is a must. too many battle fronts to fight.
2) Israel
the father of SAF, we have them to thanks for building a defense system here in 1967. look at the map of Israel, the country is a natural battleground, im sure all generals will love to fight a war with such challenging terrains.
North - Lebanon
East - Syria and Jordan (dessert warfare)
West - the great Medditerranean Sea(marine warfare)
South - Egypt
they are the only non-Muslim country in the Middle East, and war is everyday chores(i think they secretly enjoy fighting somehow...) National Service is of course a must since their threat of invasion and terrorism is amongst the highest in the world.
3) Taiwan
i have always believe China is a security threat to all nations. as said in previous posts, their stability and growth is only as sound as their Premier's mind. Communists do not need to justify any actions if they insist.like South Korea, they face problematic ties with US and China. US has shown itself to be a constant supporter of Taiwan, but apparently some Taiwan leaders like to stir shit and irritate China with pro-independence talks.as such, National Service Conscription is a great source of manpower to oppose the largest army in the world, China. their government's recent acknowledgement that Conscription disadvantages their citizens was welcomed greatly by the Taiwanese: cutting NS to 1 year. very unlike PAP's constant denial that NS disadvantages Singaporeans.
4) Singapore
there is no threat in south east asia region. Malaysia and Indonesia stands to benefit the most from Singapore's independence. heavily dependent on trading of natural resources, SEA countries have no wish to upset one of the most prosperous and safest sea route in the world.if NS is necessary, there are some issues that need to be addressed because the policies are running counter-productively to NS.
-will our economy and infrastructure sustain itself when all foreigners leave Singapore? No of course, our economy are so dependent on foreigners that it will collapse completely before the first enemy soldier fire the first bullet. a simple sanction on Singapore will kill us all, dont need for bullets.
-is our security compromised when foreigners take up important places of our companies? how many secret info has been leaking out due to appointments of foreigners? ask Chip Goodyear who probably knows how much real money we have in Temasek Holdings than any Singaporeans.
-why is NS disadvantaging Singaporean males? is there any effort by the PAP to at least keep our males on par with females and foreigners? No of course not. the PAP likes to spend more millions on propagandas than actual money to relief our NS men's monetary worries.the PAP take us NS men for granted: a disposable lot.
they love to quote kennedy "ask not what your country can do for you but what can you do for your country" my answer to them "what can the country do for me? probably not much"
