Here, from the ICC.You do realize the quote you posted has absolutely NOTHING to do with whether Israel is occupying Gaza.
https://www.icc-cpi.int/iccdocs/otp/161114-otp-rep-PE_ENG.pdfAs a result of the Six-Day War in 1967, Israel acquired control over the
territory of Gaza. In September 2005, Israel completed its unilateral
withdrawal from Gaza, including dismantling its settlements and
withdrawing its forces. Israel has maintained that following the 2005
disengagement, it is no longer an occupying power in Gaza. By contrast, it
may be argued that Israel nonetheless remains an occupying power as a
result of the scope and degree of control that Israel has retained over the
territory of Gaza – a position that the Office has previously taken in the
context of the preliminary examination of the situation referred by the
Government of the Union of Comoros.1
The ICC says Israel is occupying Gaza.
You lose again.
