I suspect the SR-71s have flown intentionally in Swedish airspace. The
Blackbirds did however run a regular route in the international
airspace, at times very close to the Swedish border.

Swedes did intercept SR-71, though. With careful calculated interception
a Swedish fighter did streak into intercept position and got a radar
lock. The SR-71 flights over the Baltic Sea and Gulf of Finland stopped
for several weeks after that with the USAAF trying to find out how the
Swedes could do that.

First, with an absolute maximum ceiling of about 65K feet, how could a
Draken have acheived a radar lock on a SR-71 flying at its operational
altitude (the ol' "in excess of 85K feet" bit)?

An altitude difference of 20 000 ft is less than 4 miles.
If the SR was cruising at 100 000 ft that's still only 6.6 miles.
Any radar has more range than that, even looking up.
