What are the cons of expansionism?

Expansionism can lead to significant geopolitical tensions and conflicts, as nations may clash over territorial claims and resources. It often results in the displacement of indigenous populations and can exacerbate social and economic inequalities. Additionally, the costs associated with military engagements and maintaining control over new territories can strain a nation's economy and divert resources from domestic needs. Lastly, expansionist policies can damage international relations and lead to isolation or sanctions from other countries.
