It's not a question of being suicidal, but rather defending your country, by whatever means necessary, even if it means dying in the process. I know that's a real sentiment because I served in the US Army for 8 years, and was deployed in Haiti and Bosnia and I was ready to fight and die for my country. Putin and many Russians are ready to fight and die for their country as well. Human beings are often willing to fight to the death, to protect their honor, integrity, resources, country..etc.
Also out of hatred for the enemy due to a perceived injustice or violation of one's humanity and dignity. To see your enemy suffer and die, dragging them into the grave with you, that's a real human response to being abused, raped, violated.
Biting the bastard's pecker off, even though you know he's going to kill you with that gun pointed at your head. You're so enraged that you're willing to risk getting shot in the head by the piece of shit that is raping you, biting his member off, and feeling those few seconds of satisfaction as you hear his blood-curdling screams, shouting in pain. The pleasure that you feel, witnessing that scumbag rapist, realize his dick has separated from his crotch, and you're there looking up with a wicked grin on your face, is priceless.
Believe me Lesh, the Russians will pull NATO, you, Anton, Todd, and myself, along with all of the people we love and care about into the grave with them. The amount of satisfaction that Russia and the third world in general will feel, seeing Americans suffer, is indescribable. They will fight us, to the death, make no mistake about that.
