Peace between states comes neither from a world ruler nor from chaos, but from a federation of equals.
The second definitive article of perpetual peace. Kant rejects both extremes: a world state would be a vast despotism, while the absence of any legal bond leaves war as the only recourse. The solution is a federation: states remain sovereign but accept common rules, like a contract among equals. A close historical model is the Dutch Union of Provinces; modern analogues are the EU or the UN.
“The law of nations shall be founded on a federation of free states.”

The stranger has a right to be received without violence, but not to stay without consent.
The third definitive article of perpetual peace. Kant calls it universal because the earth is a common sphere: the globe's finite surface ultimately limits spaces, so people must be able to interact peacefully. The right is one of visiting, not settling; hostile refusal of contact is violence, but so is the claim to take another's land. Kant's own example: Europeans colonizing America and Africa violated exactly this right.
“Universal right of hospitality, that is, the right of a stranger not to be treated with hostility when he arrives on someone else's territory.”

A peace signed with revenge in mind is not peace, but postponed war.
Kant states the first condition of genuine peace: honesty. An armistice that merely suspends hostilities while one side renews its arsenal and waits for the right moment is not peace but war continued by other means. The mechanism is trust: lasting peace requires openly declared intentions, otherwise the treaty is mere tactics. The Treaty of Versailles is the classic historical example, widely read as an armistice until revenge.
“No treaty of peace shall be held valid if there is tacitly reserved matter for a future war.”

No state has the right to impose its regime on another by force.
Every state possesses internal sovereignty, even under a tyrannical regime; external intervention would treat a people as an object rather than an agent capable of reforming its own government. Kant allows one exception: if a state has splintered amid civil war, outside help may be legitimate. A modern example: invading a country to export a political system violates exactly this principle, whatever motives are proclaimed.
“No state shall by force interfere with the constitution or government of another state.”

Those who decide on war must also bear its costs, or they wage it lightly.
Republican here means not direct democracy but a system where citizens are simultaneously legislators and subjects of the laws they make, with executive power separated from the legislative. The mechanism: those who decide on war also bear its costs, so they hesitate to start one; a monarch who pays no such price can wage war lightly. Kant saw in this structure the basic condition of peace among states.
“The civil constitution of every state shall be republican.”

Morality is not politics' brake, but the ground on which alone it can build.
Kant attacks political realism, which claims morality is a luxury of power. The argument: moral principles, such as the ban on lying in treaties, are not obstacles to prudence but its very conditions, because lying destroys the trust on which any lasting order rests. A politician who calculates only short-term advantage builds on sand. Politics that heeds morality is not weaker; it is the only kind that can promise a future.
“True politics cannot take a single step without paying homage to morality.”
