I don't know, but given the fact that the left are going so hard to convince us that it wasn't muslims and it was just a freak accident I have to be suspicious. Why are they trying so hard to convince me? Is it just the usual left wing delusion about anyone who disagrees with them being Nazis or are they covering something up because they want to keep us from resisting their suicidal policies?
But as far as coincidence goes it's a big world and bad things happen every day, there doesn't need to be a comet in the sky for that. And there is no unified global conspiracy, just a bunch of little ones that sometimes line up, sometimes don't, and much of the time compete.
We don't know enough about any of the fires to say what happened, and we may never know. ND could just be a construction accident. The St. Patricks thing could just be a nut who may have been inspired by the ND fire or just had his own private reasons. The mosque in Jerusalem could be the waqf doing something stupid again, they are not known for observing OSHA standards.
I doubt though that they are all tightly connected and being run by one shadowy group.
