Are you asking why America (along with most countries) spy? Or why they try to be good at spying? America spies because it wants information it can't otherwise

Are you asking why America (along with most countries) spy? Or why they try to be good at spying? America spies because it wants information it can't otherwise have. What are Russia's plans in Ukraine? Is Pakistan playing both sides re: Taliban? Can China shoot down a B2 bomber? We want to know and nobody and asking won't help. Why we allow them to be better at their art is obvious.
