Firstly, you have to consider all scenarios, of which the UK represents just one. Ireland doesn't really need strong armed forces, either in absolute terms or relative to its population/GDP. Its needs are dictated by factors such as internal subversion* (basically because of N. Ireland), maritime patrols/security (because we are an island**), and our peacekeeping commitments as a member of the UN and other international bodies. To the extent that such requirements cannot be met by police, coastguard, etc., then we need some armed forces, but not a lot. We're so small that we couldn't really defend ourselves properly anyway against a large aggressor. The same applies to (say) the Baltic states, which were annexed by the Soviet Union in the early months of WW II. Being a small country in the first world is generally a comfortable enough proposition. Military aggression is not the problem, but lack of economic/resource/policy control in these days of globalisation.Pappa wrote:I was thinking about this when I posted the OP and I'm pretty sure this would be the worst consequence.klr wrote:Getting back to serious matters: You would have little or no influence on any foreign state that decided to throw its weight around.

The external security issue is interesting. Does it matter? Do we need to deal with security issues outside our borders? I don't really buy the claim that we need to be in Afghanistan and Iraq (for example) to prevent terrorism within our borders. If anything, our actions there exacerbate the problem.
There's the obvious point about getting invaded by another country. A risk assessment would have to conclude that the UK being invaded by a foreign power is a low risk threat, but something that has extremely serious consequences if we did have no armed forces.
But your mileage may vary. Try to convince some Taiwanese, or Israelis, that they don't need any armed forces. Or people in many other countries with a recent memory of being a colonial power, or being otherwise manipulated or controlled by the great global powers.
