In the post-Soviet world we live in, borders are largely static. The borders of the United States, for example, have been set since World War II; The borders of the United Kingdom have been consistent since then, Britain for longer. Since the second world war, the borders of all Western Europe have been stable. In the last 20 years much of the rest of the world has had the same happen. Sure, Kosovo has demanded independence, Russia is claiming Georgian provinces, Chechnya and Tibet would like to be independent and there are some other border and sovereignty disputes, but there is no concept that the only way to maintain stability for a nation is to dominate the world around. Static borders are considered important for sovereignty and to demarcate boundaries for defense, not a sign of weakness.
In antiquity static defense was weakness. If a state had to react instead of forcing others to react, then it was weak. Lycurgus knew this when he made his third law: to make war on all neighbors, but none too frequently. Sparta was a pristine land that was almost never violated for hundreds of years, but more than intrinsic fear of the unbeatable warriors, Sparta was largely inviolate because they spent all of their time attacking others instead.
Such was the case with Athens, a paradox, wherein it was routinely invaded by land and considered weak because of it, but strong because it could go on the offensive via sea. Such was the case in Macedonia where the strength of the state was reckoned by the ability to expand into its neighbors, culminating with Alexander’s sweep across Asia. And such was the case with Rome where Hadrian received derision because of his decision to cease expansion and lay down firm, physical borders (including the wall that bears his name).
Perhaps today the equivalent to this physical domination of others being the route to safety is the mobilization of economic power to subdue troublesome nations in the form of sanctions and by the maxim of Lycurgus as applied to US foreign policy post World Wars.
