But are sleepers agents reliable enough ? Considering they would be living in peace in a modern and comfortable country, wouldn't they hesitate to act when activated?
Sleeper agents should be reliable enough, considered that they (the in the long past "recruited") want to have their family and loved ones safe -- it would really be a pity if some stupid accident happened to any of them on their way home...
Sounds morbid, yes, but rest assured, with enough "motivation" financial options and "moral flexibility" you can always motivate others, to do as demanded.
Ah, (you're) right. My game on these matters isn't top-notch.
What if the sleeper "agent" is employed by the NSA?
