this “arc” is fairly common

Does "arc" here mean "(sarcastic) flexibility"?

Thanks in advance

What makes it acute with Obama is that he started his presidency with such a soaring idealism about a world without nuclear weapons, and ended it approving a massive arms spending program. I will say, my reading of history suggests this “arc” is fairly common: it is easy to be an idealist when you don’t yet have the responsibilities of the real world, and many of them end up becoming near the opposite of what they intended to be, once they are in positions of power and influence.

    No, it means a curve (figuratively) of changing attitude from initial idealism to political reality and practicality.
