Again and again this will happen. We have signed  free trade deals around the world but if it weakens us, weakens our economy our government then those huge countries and trading pact will impose their will on our country.  The weaker we get the more we will bend our knees...this is the nature of things.  Look around you, communities dissappearing, population declining, more taxes, more fees,  people with their face full of worry...we are on sale...and one day we might find it hard to find a place to stand on that is not owned by a private entity and you have to pay fees to stand on your own country.  
A trade war with US will weaken us, bending our knees might manage it for awhile but as long as we are on this track we will continue to play this game and there will be no economic stability and without economic stability there will be lack of economic growth..except of papers.
