How Trump’s unchecked power has changed the world
Al Jazeera
Diplomatic norms, law and institutions have proven to be no hindrance to the US president. Can he really do anything he wants?
The decision by United States President Donald Trump to launch a war on Iran has left many international law experts questioning if the world order established after World War II is actually working.
In his second presidential term, Trump seems to be wielding total power without restraint, and the system of checks and balances enshrined in the US Constitution appears to be failing to limit his power.
Since Trump was sworn in in January 2025, he has ordered two unprovoked attacks on independent states, Venezuela and Iran; threatened to annex Greenland; strained traditional alliances with Europe; undermined the United Nations; and rattled international trade with his sweeping tariffs.
Previous constraints set by the UN system and international law appear supplanted by what Trump told reporters in January was a vision of power limited only by his “own morality”.
So what checks are there on Trump? Is he really free to attack states, set tariffs at will and, as leader of the world’s most powerful state, essentially dictate global policy? And if so, why are so many observers now saying his war on Iran is faltering?
