Interestingly Shimon Arad, a retired Israeli colonel, wrote on National Interest website in February 2018, 'How Israel and Pakistan Can Avoid a Nuclear Showdown?' He said:
"The advancement of Pakistan's nuclear-missile capabilities and Israel's growing military ties with India are increasing their respective military relevance for each other. In the absence of formal diplomatic relations and against the backdrop of a prevailing antagonistic public dialogue, the need for an effective and discreet channel of communication between Islamabad and Jerusalem to mitigate misunderstandings and misperceptions about each other's intentions is growing.
Col. Arad recalled that a website called "AWD News" claimed that Israel's defense minister had threatened to destroy Pakistan with a nuclear attack if it sent ground troops to Syria on any pretext. Although clearly fake (the website misidentified the Israeli defense minister as Moshe Ya'alon, who resigned in the previous May), Pakistan's defense minister hastily tweeted a nuclear threat and warned Israel that "Pakistan is a nuclear state too."
