Their sell-out leaders are willing to put the American missile shield on their nation's soil with the foreknowledge that in WW3 it will mean the Russians and Chinese will selectively target the Czechs with about ten times as many warheads as are needed to safely assure their extinction.
This is why people have democracies. The peasants are no rocket scientists but their simple horse sense is a million times more reliable than the elaborate and compromised loyalties of their traitorous elected officials. They know it's a bad idea. You can put lipstick and high heels on that old nag but the horse still won't run fast and they know it.
Accepting any part of the American BMD sites on your country's living space is tantamount to signing your own death warrant and these people feel that fact in their bones.
As demonstrated a hundred times in recent years by science, the subconscious mind knows itz coming long before it gets here. At some profoundly deep instinctive animal level, the Czechs know a global thermonuclear war is approaching. Their leaders can talk themselves blue in the face with sophistry but at the end of the day the basic judgement of the common man is better than their elegant theories and social engineering. Humans practice deception on each other in even the simplest of matters and it usually means telling others ... don't trust your gut instinct. Trust me instead. I'm edjumificated n'stuf. Look at all my certificates and qualifications and awards. That means, I'm highly intellamejent n'stuf, more anti-ignorant than thee and whatnot. At the end of the day, the diplomats are just ass-kissers who want to stay in the good graces of the Americans, whatever the long term consequences are. They know they'll probably be one of the lucky ones inside a good deep vault when the time comes.
