No. Social democracy needs superprofits from the periphery to fund the core. Capitalism requires exploitation to function. If every nation is the core, who gets exploited? The surplus value does not exist. When accumulation slows, the bourgeoisie abandons reform. They choose fascism to protect property. The SPD proved this when they sided with reactionaries against workers. Reformism tries to manage a system built on violence. It cannot work globally because the economic base forbids it. The only path is revolution. Seize the means of production. End the imperialist chain.
