UN Collective Security

according to realism... when wouldn't a state go to war?

"insecurity can be capped at manageable levels, so long as no state has significantly more power than another state"

what evidence do we have for this BoP?

in this classic BoP system, we have several key rules

so, Realists would argue that by following these rules throughout this long period, states produced a balance that created stability

after WW1 we began to see efforts to find an alternative to the BoP, this came in the form of COLLECTIVE SECURITY
- it is a LIBERAL idea

collective security: main ideas

History of Collective Security

League of Nations (1919)

why did the League fail?

and then came the UN in 1945 with almost universal membership
but is the UN a collective security arrangement???

But on the other hand...

SYRIA CRISIS
- why no collective security response?

UN not set up to deal with internal/civil war

why does Russia veto action in Syria?

could argue that Collective Security is being prevented by the very structure of the UN- but how is the UN structured?

How about the General Assembly?
