¿Que esta pasando en Venezuela?

Today I was looking for a good source that explained the trouble of Venezuela in a simple but accurate way. I found a really good video that expresses the problem in a simple way.

 There are also other sources that say totally different things and that express that everything is the students fault. If you want more information about this point of view and about how the minister of interior Miguel Rodriguez expressed it go to: http://www.tiempo.hn/el-mundo/noticias/venezuela-gobierno-culpa-a-oposicion-de-adiestrarse-en-mexico

Finally the las point of view is from Raul Castro, President of Cuba, who expresses that what is happening in Venezuela and Ukraine is the US fault. http://www.martinoticias.com/content/cuba-castro-apoyo-venezuela-maduro/32313.html#page=1
