Is it possible that Hamas had recruited converted engineers, physcians or otherwise highly educated people from Europe in order to boost capabilities ?
This is not, in my view, a silly question
We know even from basic history that military planning went along with professionalisation of officers and in the 18th cebtury it become very advanced thanks to the intrododuction of scientific, and mathematical, thinking in the officer instruction.
But this was possible in Ashkhenazi communities, in reformed Christian and, since XIX century, in far east countries, because the religious mebtality was determinant: a mind cannot follow, or reject, "logos" at will
More concretely, we have seen that historically hamas managed to act isolate attacks, small unit raids and ghazi charges with screaming human masses, but until 2023 they did not manage to conceive, plan, fund and execute a complex plan
Let's try to think about it
Hamas, an organization of integralist muslims who dislike logic and the ability to discern by intellect and exoeriments the truth from the BS, managed to
a) conceive a complex plan involving an artillery preparation, movement of fence cutting equipment, paragliders and a fleet of Pick ups . The very idea of artillery prepartation requires historical knowledge - something Hamas cannot do- and a mind trained to think in terms of propedeutical actions that render possible following ones
b) managed to conceive a scheme to acquire the materiel without being fully noticed by Israel and to train shooters in a less improvised way
c) managed to keep , in an environment full of israeli informers, secrecy until the very final hour
I have reasons to think that all this was NOT, or not only, fruit of the mind of original members, but that one or more person, with university education and in his/her young ages used to analytical planning, , had converted to islam and had brought his /her pre musilm logical mentality to the terrorists.
thealternative is that some muslim, but not arab, maybe a professional officer, has helped in this operation, but in this casethe country to whom that officer belong(ed) had committed a clear act of war.
We know, by the way that the integralists are present and active in Universities and, at least in France, they try to convert young men from STEM disciplines and it is a fact that from 2003 to 2023 their rockets have improved, as someone expert in aeronautical engineering had worked about them
