Arms Race: This refers to a competition between nations for superiority in the development and accumulation of weapons. It's like two rival football teams constantly trying to outdo each other with better training equipment and strategies.
Nationalism: This is a political ideology that involves loyalty and devotion to a nation. It's like being a die-hard fan of your home team, always cheering for them no matter what.
Imperialism: This is when one country extends its influence over another through force or diplomacy. Imagine if our football coach started controlling other teams too, not just his own.
