Scotland probably doesn't need a large air force, army or navy but the trouble is the SNP have "promised" that all the present bases will be kept open to try and maintain the mirage that come independence nothing will change - those that have jobs will keep them and those on benefits won't be limited to the measly 1% increase that the horrible UK government is imposing - under independence you'll get a bigger rise than that
.
But and it is a big but who is going to pay for this largesse - oil won't and anyway come 50yrs from now that will be a faint memory so you can't base independence on a diminishing finite resource
Fortunately the majority of Scots aren't stupid and see through the lies ( Salmond " we have legal advice about Europe" on no he hasn't) and rhetoric of the SNP and the polls remain pretty consistent at only 30% or less for independence.
