Sometimes, running from a fight intensifies the threat and widens the fight.
Most times, running towards a fight lessens the confrontation and may even prevent a fight.

Russia has proven to be a very dangerous petulant child. Anyone who has raised children knows the sooner you deal with the problem the better and, if you stick your head in the sand and do not deal with the problem, there is a risk you could raise a sociopath.
The US tried very hard to stay out of the two biggest wars of the 20th century, but got drawn in anyway. If the US had a reasonable sized military in 1939 and jumped into the war in Europe when Poland was invaded, Germany would have been stopped before it could get very far. In 1939 the US Army was smaller than Finland's and the US had just started rearming.
Sorry, but after the big show in London the British start to realise that they have exceedingly little to offer. After successive budget cuts the RAF is just a shadow of its former self and even the training regime of their own pilots has been cut to the bone.
As with the tanks there are some countries that love to showboat and others that are more discreet.
As to targeting civilians, that's extremely nasty and most likely a war crime, but may I just point out that both the US and the UK have also employed this policy of terror bombings in the past?
Every power that could bomb civilian populations has done it. Germany did it to several countries, but is best remembered for bombing civilians in England.
The RAF determined that daylight precision bombing of targets in Europe, so it employed nighttime bombing where the best they could hope for was hitting somewhere in a city. The USAAF put in a massive effort to do precision daylight bombing in Europe with less than ideal results. The problem was the Norden bombsight was nowhere near as good as the US claimed and a tendency for creep back. Normally the lead bomber's bombardier would try to aim for the target and the follow on bombers would try to release their bombs over the same point. But the other crews being flown by human beings, and German flak being very intense, there was a tendency to release the bombs as early as possible. The next bomber in line would release a few seconds early, followed by the next bomber releasing a little early, etc. which led to the bombs being scattered a long ways from the target factory.
Over Japan the US tried high altitude precision bombing with B-29s only to find the jet stream is so strong over Japan the bombs would get blown unpredictably off course on the way down and they rarely hit the target. So Curtis LeMay stripped the bombers of their turrets to save weight and sent them in low at night. They did to Japan what the RAF did to Germany.
Over Japan the B-29s did manage to knock out a lot of Japanese industry because they managed to destroy entire cities. The fire storm that hit Tokyo did more destruction than the nuclear attacks.
Over Europe strategic bombing was not very effective at knocking out industry. Where strategic bombers were most effective was in the rare occasions when they were used to bomb battlefields. The 8th Air Force was called on to help the US break out at Normandy in Operation Cobra. They hit the German force concentrations and did massive damage. Oberst Hans von Luck was in command of that sector that day and he details in his book the mess he tried to pull together as the Americans started to break out. He came across Tigers that had been flipped on their backs by the bombing.
The strategic bomber forces rarely agreed to support ground forces. They saw their mission as crippling industry and they didn't want to be tied to the ground forces. They fought hard to be seen as an independent force.
I agree about the war crimes aspect, but bombing civilian areas has been proven over and over again to be counter productive when the civilians feel that their side has the ability to fight back. There were some times early in the war when bombing civilian targets drove an enemy towards capitulation, but it was both when the technique was new and it was against opponents that were outmatched to begin with.
Similarly the Sirens of Jericho on the Ju-87 Stuka struck fear into enemies during this time, but they were removed around the time of the Battle of Britain because they quit causing fear, caused added drag, and tended to alert anti-aircraft gunners you were coming if they weren't already alerted.
The US was dumb enough to repeat the same mistake with civilian bombing in Vietnam. Hopefully the US won't do it again, but who knows what the future holds.
