sneaking weapons into some countries is harder than into others, making things that fly long distances gets exponentially harder as distance goes up linearly.
That's true, but when things get cheaper you can afford to lose a lot of them. Suddenly every container vessel is suspect. That trick has a lot of potential and harbors are relatively soft targets and easily accessible from just outside international waters. You could do a shitload of damage to most countries by just targeting a few key locations well within the reach of a basic drone and what sub $1000 drones can do is changing by the day.
Armor and artillery are basically useless against a fleet of seaborne drones.
