I don't think there can.
The terrorists who have claimed responsibility for this bomb are "New IRA", also called "Real IRA" - I don't know whether this group is the same as "Republican Revolutionaries", named on Twitter last night. Their most recent previous activity was July 2018, and there have been a string of earlier outrages. This group opposes the 1998 Good Friday Agreement and wants to drive the Protestants from Ireland. What they want is ethnic cleansing.They are funded with drug money. In effect they use their power to enforce control of the drug supply in an area by acting as vigilantes against other drug dealers. If a reason for this attack is to be found it is quite possible it should be regarded as a drug war.
The nearby Fountain Estate in Derry/Londonderry is a few streets which are protestant on what is the Roman Catholic side of the River Foyle (and it is shocking that we can talk about sides of a river in this way). The residents of The Fountain have been subjected to decades of intimidation. Bluntly, anyone with any sense would have moved out years ago and got on with their lives. However The Fountain has maintained its community. And yes, they push back, and they are probably not very nice in this. There are flags. There's a security fence around. They paint the kerb-stones (red, white and blue). And there are murals - paintings on the side of buildings - which some regard as provocative. Curiously the idea that The Fountain is "under siege" is a credible image. They really are completely surrounded by people they regard as the enemy, by a community who wants them gone, cleansed from Ireland, and they do get a lot of aggression directed against them. I'm (mostly) English, so I suppose I could visit The Fountain, but I would be very cautious about walking through the streets to get there. (Taxis tend to serve either protestant or catholic communities, so even the idea of taking a taxi in isn't as easy as it should be. Maybe a taxi as far as the edge.)I really do mean I would be frightened walking in much of the Bogside, basically anywhere outside the citadel.
Just look at the picture: slogans, painted kerb-stones, boarded up houses. This is a very poor community. You can buy a house for next to nothing. There are few jobs, no obvious reason to be there, and a credible threat to your life every time you enter or leave.
