Wouldn't take very many at all, we've now learned these past four years (and even the past 2 months). All you need are drones, that are pennies on the dollar cheaper than trillion-dollar militaries. Depending on the munition, a single bomb we drop on Iran could cost between $40,000 and a couple million dollars. Think of all the high-end drones you could buy instead.
Everything is changing. Including our influence.

You make an incorrect conclusion which is unfortunately both quite popular and incorrect among westerners who read two and half editorials about Russo-Ukrainian war in some NYT/WAPO/whatever and think they now understand modern warfare. The reality of the situation is that drones are a very useful tool, but any side achieving actual air supremacy would result their fighters and bombers cruising over frontline and enemy towns on low altitudes taking out any high-value targets at whim. The situation would be similar to boots-on-the-ground phase of The Iraq War, resulting one of the sides to rapidly gaining ground and winning the war. Keep in mind that the cited "40k per-hour" price is quite cheap compared to per-hour operation cost of any kind of big ground force.
In fact, last thing US wants is to be in Russia's shoes unable to meaningfully advance into the territory of by all measures much weaker enemy.
That isn't really accurate, small drones are enough to antagonize regional neighbors. They are far from being able to project influence, stabilize international trade, or even remotely protect a territory from an enemy that isn't concerned with civilian casualties.
Drones are not a strategic weapon. When you talk to the Ukrainian military, with their actual expertise in drone warfare, the general consensus is that drones are an inferior replacement for artillery (note that ex-Soviet military systems are a lot heavier in artillery use than NATO military systems) that they use because they can't get the artillery shells that they need but they can get drones in sufficient quantities. It hasn't enabled any strategic breakthroughs in the Russo-Ukrainian War, it is merely served to lock in the grinding stalemate it's been in since October-ish 2022.
The US war on Iran also demonstrates the problems of drones too: the US is currently able to wage a war 6000 miles away from its shores, because of the use of an awful lot of weapons systems that aren't drones. Iran is unable to dislodge that military, or even meaningfully impact its ability to carry out said war, not 100 miles away from its shores, despite a heavy use of drones to attempt to do so.
The war also demonstrates another big issue... the continued delusion of many civilian and military leaders that strategic bombing alone is sufficient to win a war despite this failing literally every single time it's been attempted in the past 100 years.
In the Russian-Ukrainian war the GPS guided shells that the USA was sending to Ukraine cost about $40k a pop, where as you can get at least a dozen drones for that price.
Even the fanciest self propelled artillery is getting destroyed by these little cheap buggers.
