Trump’s proposal to rename the Gulf of Mexico as the 'American Gulf,' his push to make Canada the 51st US state, and his plan to buy Gaza while forcibly relocating its Palestinian population must be viewed within the broader geopolitical shifts of the 21st century.
With such positions, Trump is effectively dismantling the principles established by the Peace of Westphalia (1648), which laid the foundation for the modern nation-state and enshrined the recognition of sovereign borders. By dismissing the territorial integrity of nation-states on a scale not seen since World War II, the US president is trading diplomacy for might-is-right politics.
Redefining borders and partitioning territories have never been preferred strategies for governments. More often than not, diplomatic negotiations and peaceful settlements are pursued to resolve disputes and delineate contested regions. The act of drawing arbitrary lines to separate nations, communities, and ethnic groups is a perilous endeavour—one few rational actors would willingly undertake unless the intent to provoke conflict and confrontation is already in place.
The division of Germany and Eastern Europe among the victorious Allies after World War II was a gruelling process that ultimately saw the Western powers acquiesce to Soviet control over Eastern Europe. Perhaps Joseph Stalin’s most consequential manoeuvre in this regard was his reversal of prior agreements concerning the future of Poland.
