Could this really happen to start WWIII?

Israel feels threatened by Iran and attacks the nuclear facilities. Iran retaliates and launches missile attacks at Israel. Jordan and Syria attack Israel due to US help of Israel. US already has Iran on two fronts(not by accident i believe) and fortify the borders to stop aid from coming in. NK takes the opportunity and invades SK. Japan re militarizes and attacks NK and China. Russia doesn't want US control of Irans oil and attacks through Afghanistan. China stay 'neutral' but supplies NK with equipment. Could this be wwiii and escalate to war with china? Also who wins US and NATO or China russia iran and others?
