For the 10th time this term its his go-to.

Same as a child knocking over sand castles at the beach after others refuse to play with them due to their prior behaviour.

how does one describe this tactic?

"It's the american way"

History rhymes.

the destruction of Warsaw did not serve any military or colonial purpose; it was carried out solely as an act of reprisal.

German forces dedicated an unprecedented effort to razing the city, destroying 80–90% of Warsaw's buildings, including the vast majority of museums, art galleries, theaters, churches, parks, and historical buildings such as castles and palaces. They deliberately demolished, burned, or stole an immense part of Warsaw's cultural heritage.
