The Treaty of Versailles meant peace at the times, as it ended the WWI. However, it also established very harsh conditions for Germany (high war reparations), which later led to Germany's poverty and the rize of Nazis to power : so it's blamed for instigating (causing, leading to) the WWII.
The Treaty of Versailles also brought a big land loss for Germany, Austria and Hungary.
I think it is the last one if not then it is the first one
Every government has to have their own responsibility. You can't have two governments branches doing all the work while one sits back and just watches. It is the governments responsibility to keep this nation safe and secure, that means everybody must do their part.
i really do hope this helps :)
