You could say the same about the guy in a call center in India trying to pull a tech support scam on you over the phone. Yes, he's probably making the best choice he can for his own livelihood, probably the same thing you would do in his position. No, that doesn't mean you should trust him.
Just as you have to treat all Chinese companies as under control of the PRC government and all Australian companies as compromised by their security services, you have to treat all Israeli citizens as under the control of the Israeli military. Any adult can be conscripted and they have a history of disguising military operations as civilian ones. Someone might tell you they left the Israeli military 10 years ago and they're probably telling the truth, but if you make a habit of believing that statement you're going to get burned.
