In the year 90 BCE , was Carthage still Rome's biggest enemy?:

By 90 BCE, Carthage was no longer Rome's biggest enemy; in fact, it had been completely destroyed in 146 BCE, well before 90 BCE. The Romans had decisively defeated Carthage in the Third Punic War, resulting in the city's total annihilation and the end of the Carthaginian threat. Instead, by this time, Rome was facing new challenges, including conflicts with various tribes and groups such as the Social War, which arose from discontent among Rome's Italian allies. During this period, Rome was transitioning from a city-state to a dominant republic, and its attention was shifting towards internal strife and expansion. The conflicts with the various Italian tribes over citizenship and rights showcased the complexities of Roman politics and alliances, revealing that the real battles were happening closer to home rather than against a vanquished foe like Carthage.
