Let them fight.
Who cares about Ukraine? Which significance does it have for anybody that is not from Russia or Ukraine? I don't see the West doing this for Ukraine but just to get a message across to Russia.
Ukraine has no other option than balancing between the West (EU) and Russia. It cannot pick one side fully if it wants to remain as it is today, meaning united as we know it.
No my dear this is not the case this development will surely cause effects upon the regions around it, if you are considering it as a simple matter b/w Ukraine & Russia than you are mistaken.
Its not about Ukraine but about 'Black Sea Region', just look at the map this situation will have a direct impact on Turkey, which will Indirectly effect Middle East as well, more complication ahead in regional politics ..... lots of possibilities ....who knows what will happen next
Basically, it was a soft encroachment of EU and US in Russian backyard, which Russian retaliate in a bit harsh manner. If the future events occurs as expected, than US and EU might not respond militarily but would prefer a strategy some what similar to first Afghan war.
In that case, Turkey is the only Nation in the region having reliable defence apparatus in place, but currently suffering from
internal political turmoil, to influence the future events in this region
a strong, progressive and developing ally of the west is necessary.
Tukey is a member
NATO alliance and could be helpful to engage and organize Tatar population in the region.
Syria is an old ally of Russia having sizable
Kurd populations, this factor will be valuable for Russians to disturb or influence Turkey, but KSA don't like Assad regime .....
now say who cares .....
