A satellite-internet connected stationary gun aimed at an intersection they know this guy drives through often is a magnificent tool for agent safety.
These intel agencies aren’t idiots. If they knew a hit and run would be safe and easy they woulda done it. They’d probably prefer having operatives safe and alive instead of tortured and dead so they can continue operations.
And we have no idea how high tech this is. For all we know it’s a standard high caliber rifle attached to a pretty standard mount, with a live feed scope and a trigger puller. A team of engineering freshmen could develop this kind of system given the equipment. If Israel or the US are behind this they have probably had this tech for over a decade.
You still need just as many operatives in country for this fantasy, but you also need to be able to smuggle high end equipment and set it up and test it, this are additional complications that increase the risk of failure and capture nor reduce it.
You need to set it up, test it, move it to the target all without being detected and still have a backup plan and local observers to support it.
It adds complexity and risk it does not reduce it and intelligence agencies dont like complicated.
