IMO you dont appreciate what a country's perception of its national Security means.....It simply means that all means within its power will be used to protect the country and its inhabitants .
There are 2 issues of perceived National Security threats here:
(a) That of the Ukraine (b) That of Russia
IMO the latterb is not been appreciated/accepted by the West and in particular the USA who uses/leads NATO as a tool to implement its own national security issues which in this case to minimise Russia's (its no 1 enemy because of Russia's Nuke capability) ability to service/add to its current Nuke arsnal and its ability to deliver Nukes supersonically avoiding the US missile defence shield.
The Cold War has been all about the balance of power between the USA and the then USSR and that even a first strike by either would automatically imply MAD (Mutually Assured Destruction)
All that changed. in 1991 when the USSR imploded but as Russia recovered economically via its Petro-Economy, the US egged on the ex Warsaw Pact countries to join NATO (with good reason to secure their newly acquired western status)
While Russia tried to limit NATO's eastward expansion, it also developed Hypersonic ICBM which challenged the US newfound hedgemonic status.
Russia's red line was NATO's further encroachment around the Black Sea; namely to the Ukraine. Georgia & Moldova which now leaves the Ukraine taking the brunt of the tension between Russia and a US led NATO.
Was Gorgia intelligent to give up its 2 Oblasts to Russia in Aug 2008? I guess in relative terms (ie Georgan outcome vs that of the Ukraine) ...yes but in Ideological terms that justifies the wasting of millions of lives and billions of wealth,,...then yes.....so take your pick.
Georgis simply cant join either the EC or NATO because of border disputes and its legal/political system . In that sense Russia has enforced its Red Line.
Similarily in Moldova
So, IMO there's alot at stake for all the "Stake Holders " innthe outcome of this Ukrainian war which, IMO, has the propensity of expanding even further with the Doomsday Clock indicating that a Nuke War is the nearest ite ever been!!
How absurd and how absurd for posters on this thread to advocate an escallation of this war.! We need a ceasefire now and let the negotiations begin and then let's see who the real power brokers are around that table.
Imo the Pentagon/CIA will feature prominantly at that table despite the bigots saying that this is not a US/Russian proxy war.
