The horizontal axis is the one campism keeps. It runs from aligned with the Western bloc — the United States, NATO, the states and economies inside that order — on the left, to aligned against it on the right. This is a real axis. Empire is real, and the US-led one is the largest. Nothing here pretends otherwise.
The vertical axis is the one campism throws away. It runs from power held over people at the top — secret police, jailed dissidents, crushed strikes, disappeared journalists — to power devolved to people at the bottom: assemblies, councils, federations, liberation movements that answer to the populations they come from. It asks a single question of any government or movement: what does this power do to the people under it?
Those two questions are independent. A regime can be anti-Western and a prison. A regime can be Western-aligned and a prison. Knowing the alignment tells you almost nothing about the cell. Campism is the belief that the first axis can stand in for the second. It cannot — for the same reason the left/right line cannot stand in for a 2×2.
