A draft is where the government uses the police to force peaceful citizens to fight in (and die in) wars that the citizens do not agree with. The proper name for such a hideous concept is slavery.
No. Under capitalism any form of “drafting” — that is slavery — is illegal. Under capitalism no government can initiate a war against other countries, by forcing its citizens to fight or pay for such a war, if they do not wish to of their own free-will.
In a capitalist country there is no draft, in which governments can force their citizens to fight wars — since they are prohibited from initiating force against their own citizens — and by extension citizens of other countries.
If a capitalist country is attacked it will retaliate and defend itself, as it does with any tyrant, brute, and monster, by means of the most powerful kind of army possible: a voluntary army of free men who wish to live their lives as free-men and not as slaves.
