Funny how alliances are made within an alliance.
Not funny but logical and quite common!
Wherever humans come together there is group building...even if they are in the same party with the same goals...opinions just differ...how about which way is best....and how to go about it...
Right now the northern group thinks their way to handle the crisis is best...they want some changes to the base of the organisation, some adapting to the treaty...so that such a catastrophe can't happen again.
Other countries don't see it like this...so now there is discussion, trying to convince and searching for likeminded allies to strenghten the own camp to get a majority in either this or that direction!
All part of a healthy democratic process...as there is, contrary to some conspiracy specialists, no faceless, grey entity in Brussels which decides as she sees fit for all of us.
The reality is much harder and more difficult...
Just think your own parliament with it's parties and coalitions multiplicated by 27!
