I’ve built more tunnels than his company.

And most of those were just fucking around because I could, not even for a specific purpose.

Lpt: don’t dig without telling someone exactly where you are,and without a noise maker.

Hamas is rather good at building tunnels in the hostile environment of sometimes being bombed. If they’d have funds and modern tech … ah, well, they’d embezzle the funds and use that tech for something destructive, but if they wouldn’t, they’d be great tunnel makers.
