Maple - UNSCR 678 was the authority to use force to remove Saddam from Kuwait - this was based on the previous resolution
which called on him to withdraw from Kuwait. UNSCR687 was the ceasefire document which outlined the provisions under which Saddam would disarm post the war .
The breaches of 687 however didn't in any way allow 678 to be used again because 678 was incredibly specific in that it allowed for military force to be used for his removal from Kuwait
but it didn't authorise the invasion of Iraq . It wasn't a blank cheque for war against Iraq at any time.
The breaches of 687 were serious but if you follow the wording of the resolution - the length of time that this resolution
could run for was almost unending and could hardly have been
within the spirit of what the U.N decided in 1991 . The purpose wasn't to turn Iraq into a destitute state.
Effectively there needed to be a new resolution authorising force against Iraq. The 'spikes of activity' carried out by the co -allition previous to GW2 to soften up the Iraqi air defence network clearly didn't come within the terms of 687.
