In a timeline I'm thinking of where Egypt stays majority Christian, I'm considering an event in the 20th Century where a hardline right wing government gets into a war with Arabia. As tensions really erupt, they level Mecca with missiles from the Sudanese coast.
Assuming few butterflies and global Islam is in a similar place to how it was in 1980s OTL, how would Islam react to this intellectually? Obviously there would be extreme anger and anti-Christian feeling, but are there Koranic or Hadith implications? Does any of this play into eschatology, pilgrimage duties or anything else I might not know about?
