It is too complicated to discuss here. First of all, the naval bases, gas pipeling infrastructure were build in Soviet times using resources of whole Soviet union. After its collapse in 90th everything became messy, but old strategic interests were respected.
These events has very simple cause - too avoid any shift of control over strategic resources of former Soviet Union to pro-EU oligarchy and eventually EU capital which which Russia cannot compete.
The other question is a moral one - does the interests of Russian oligarchs, controlling Gazprom, who "inherited" Soviet infrastructure should be reinforced by military operations?
At least it is not an ethnic conflict, just conflict of interest.
