"No nation is so great as to be able to afford, in the long run, to remain outside an increasingly universal League of Nations"

In this quote, Hjalmar Branting is highlighting the value of global cooperation and unity. He argues that no country, no matter how effective or wealthy, can sustain its success if it picks to isolate itself from the remainder of the world. Branting believes that in order for a nation to prosper in the long run, it must belong of a universal League of Nations, where countries come together to address global concerns and work towards typical objectives. By belonging to this league, a nation can benefit from the cumulative strength and resources of other nations, leading to mutual development and prosperity. Branting's words serve as a pointer that in today's interconnected world, isolationism is not a sustainable choice for any nation.
