Bcp38 is not the issue. It is only the trigger, and as long as one network
in Elbonia allows spoofs, that one network can marshall  100s of gbs of
ddos power.  Years of telling people to do bcp38 has not worked.

The issue is for you and your neighbor to turn off your reflecting udp
amplifiers (open dns relay, ssdp, ntp, chargen) and generously block
obvious ddos traffic.  A healthy udp policer is also smart.  I suggest
taking a baseline of your normal peak udp traffic, and build a policer that
drops all udp that is 10x the baseline for bw and pps.

Bcp38 is good, but it is not the solution we need to tactically stop
attacks.

This is not pretty. But it works at keeping your network up.
