for sure there is a trend happened recently refer to the architecture of war , first of all it isn't a movement in my point of view, it is a trend due to the sacration of military actions in countries like iraq , lebanon, afghanistan, syria, and so on .
from the above i think it is a (sheltered architecture), or the (tin sectors), (the slum sectores), which you can find in every country suffer from the conflicts explained before ...another point of view that this could not be a movement but a result and consequences of political actions, to be a movement it should draw a continuous line repetitive as i remember .
thank you for engaging me in this interesting subject i will be grateful to help if it is a research topic .
