Minimize vs. Minimise
This is a spelling and house-style choice, not a meaning distinction. British English permits more than one convention, so do not label “minimize” universally American-only.
Both spell the same verb. “Minimize” is standard in US English and is also accepted in British -ize styles; “minimise” is the usual British -ise spelling in many publications.

Quick tests
Decision test
Does your target publication specify -ise or -ize spelling?
If yes: Follow that house style consistently.
If no: For US-oriented copy, “minimize” is the normal default.
Caveat: Do not universalize one British spelling policy; both -ise and -ize conventions exist in British publishing.
Examples
We want to minimize unnecessary delay.
The -ize spelling is standard US usage and valid in some British styles.
The UK publication chooses minimise throughout.
The -ise form matches that house style.
The editor checks all -ise/-ize verbs for consistency.
Consistency is the practical decision when house style controls spelling.
