Remember that Egypt is a hopelessly corrupt developing country. It doesn't really matter who is at fault. The matter would be decided by an Egyptian court where the judge will rubberstamp whatever narrative and claim the government wants to present.

Remember that Egypt nationalized (stole) the canal in the first place from the UK. The only reason they were not bombed to oblivion was that it suited US goals of further humiliating former European imperial powers after WWII. Egypt operates tha canal as spoils of war and their only real concern would be if shippers begun considering the risks of relying on the Suez authorities higher than going through the Horn of Africa.
