Americans do build things, but we do not do it in other nations. Unless you are referring to our colonial era. The wall we are building to protect us from large immigration sizes is on US owned land. It is not 10 miles into Mexico. We had proposals for bases we wanted in Iraq. We did not just start building, we sent a request to their parliament. Mind you their parliament is not working. So, since under 242, the land you want to build on is still Palestinians until negotiations end, why don't you send a request to the PA to ok the building. Then no one will complain.
