Not hard to forge identity.
For that matter, zionists need to put up a brave front. Everytime they lose any of hteir troops equipment etc they'd hide and obviously mossad can create forged identity, create coverup stories, many media are run by them, they got agents in many countries, not too hard really for just about any semi-competent state actors.
It goes other way around too. It shouldn't be too hard for Iranians to pose as Turks, Azerbaijanis with forged but credible identities and enter zionist terrorist entity, collaborate with Hamas, supply weapons to Hamas, supply intelligence, sabotage zionist military and intelligence operations and these are only two neighbours of iran i mentioned. there are literally hundreds of other nationalities and ethnicities that could be used in more than one ways. any semi-competent countries can do this.
