Hi!
Could somebody please explain to me how contested and changing borders challenge a state's sovereignty? Thank you!
Well sovereignty is the notion that you have authority and supreme control over a fixed population and defined territorial region right?
If that is the case then Russia's (or "pro-Russian militant's") invasion of the Crimean Peninsula, Ukraine, in 2014, is contesting Ukraine's sovereignty as they seek to take rule over the territorial area. This challenge of Ukraine's sovereignty is further seen when 50 pro-Russian militants and 20 other civilians invaded and successfully controlled a Navy airbase in Novofedorivka, March 2014.
So basically when a state's "power" over that recognised territory is being "disputed" by another state you see how it challenges a state's sovereignty.
(Sorry for the vagueness, I'm trying to remember this from last year!
