What do you think john adams would like and dislike about today's us government?

The thing he would probably dislike the most about today's U.S. government is the involvement in foreign wars including the Iraq and Afghanistan wars. This is because John Adams, while not strictly a pacifist, advocated peaceful resolution of conflicts, and disapproved of the excesses of war.

For example, during his presidency, he did build up the army and navy preparing for a possible war against France, but in the end he signed the Treaty of Mortefontaine, which prevented any further escalation.

china unilaterally claims the entire south china sea as sovereign territory, then builds artificial islands to bolster its claim. it suddenly activates an air defense identification zone over the east china sea, and threatens to down any aircraft that does not report its position. it builds roads into indian territory, then redraws the maps to show that it is actually chinese territory. the people's republic under president xi jinping is quickly becoming the bully of asia.
