A military strategic question

[mapuc]

I guess you have heard about what happen in East Ukraine earlier today.

Little background to my question.

I have on several friends and friends friends wall read things like

It about time we send NATO troops to Ukraine. Here some just want the troops there as a powerful message to Putin

while some want NATO troops to engage the Russian.

Reading such things scares me.

I have posted answers on some of these walls.

I could be wrong, I only remembered what I saw, heard and read what a war between NATO/USA and Russia would lead to.

I wrote that a war would go from conventional to nuclear. If not the leaders came to common sense before a war started or ran out of control.

So was I correct from a military strategic view ?
