In other words this is all for domestic public consumption to distract the people from the problems caused by socialism
As a distraction this is a risky policy.
If you keep making war noises the public expects you to go to war. You have maybe a year to either fish or cut bait.
But if you go to war you are going to get your tail kicked.
And when the country you are threatening is right next door they may not wait for you start something. They may just decide to take you at your word and start the war you wanted as a diversion.
