I thought you had left it aside??

As far as elections go, fixed term parliaments act put that 5 years away, May decided the polls looked so good for her, she wanted to circumvent that act for her own gain. The rest is history.

The understanding of that outcome is still ongoing and the conservative party is still in shock over events  The electoral dice fall wherever they fall. There have been minority governments before with or without the DUP this one is likely to have a similar life span.

The incumbent conventionally has first chance at forming a government which may or may not be one in which it has an overall majority either on its own or with some form of arrangement . Heath tried in 74 and failed, Wilson picked it up.Both were minorities. 

One of the problems with the DUP deal is the way in which the arrangement is clearly, publicly one based primarily on cash, offering seats and votes for about a 100 million each. 

The peace agreement is also put in jeopardy when one party is critical to supporting what is supposed to be an unbiased broker to that agreement especially at problematic times.

Political rhetoric isn't necessarily meant to be taken literally.  If the amendment was meant to try to peel off pro European Tories, at this moment in time  It wasnt likely .A party in shock, isn't likely to respond.
