1. Smiley says to his Soviet arch-enemy Karla: "Look, we've both spent our lives looking for the weaknesses in one another's systems.  Don't you think it's time to recognize there is as little worth on your side as there is on mine?"

This is an incomprehensible statement, especially coming from a British spy who is intimately familiar with the Soviet "system," the one that murdered tens of millions and subjected its population to decades of terror, targeted famine, gulags, bread lines, corruption, environmental despoliation, anti-Semitism, and -- which should really horrify leftists -- massive income inequality between the nomenklatura and the proletariat.  In the balance, Britain had "Benny Hill" and crummy Vauxhall cars.

2. The mole (traitor) says to Smiley: "I had to pick a side, George.  It was an aesthetic choice as much as a moral one.  The West has grown so very ugly, don't you think?"

This is a character speaking, but you can imagine a certain segment of the audience nodding their heads, condemning the ugly consumerism of the West and its ugly imperialism, ugly Halliburton, ugly Guantánamo, ugly blood for oil, ugly Bush Lied, Kids Died.  The line presents a ripe opportunity for Smiley to respond with a defense of Western values, but in the script we read: "Smiley doesn't answer.  A moment of silence."
