When a bully or bad person threatens something if you do not do something they want you to do, they have already decided to do it and eventually will do it. If you comply with a bully or bad person who threatens you to get you to do something, they will get you to comply with that and threaten you again for the next thing they want you to do. On and on it will go until there comes a time they will just do what they have threatened in the first place because they actually want to to it from the start. You cannot appease a bully, terrorist, or other bad person who threatens to get what they want. Also, eventually whether you want to appease them, there comes a time when you cannot do so as they just push too far.
A bad person, terrorist, or bully cannot be a friend, then an enemy, and then a friend. As they say a “snake” is a snake and they will act as such because that is their nature. Putin is a terrorist and bully. His governing style is mistreatment of his own people and soldiers.
