I’d just like to interject for a moment. What you’re refering to as GNU, is in fact, GNU/Linux, or as I’ve recently taken to calling it, LINUX plus GNU. GNU is just one replacable suite of libraries ,not an operating system unto itself. It is but another free component of a fully functioning Linux system made useful by the vastly complicated hardware to software communication protocols. Shell utilities and “vital system components”, are not enough to be called a full OS , as much as some 80s guys that created POSIX would like it to be.
I’m guessing that the intention is "If Israel can handle missiles from Lebanon and Gaza, why can’t they handle 10 times the normal amount from Iran.
It’s a numbers game , and w/o the US and Jordan helping to intercept them , the civilian damage would be much much much more extensive; and only one of these 2 can be true - Iran has terrible terrible terrible aim, or they targeted civilians.
