Donald Trump is withdrawing from the Paris climate agreement because he wants to lower environmental standards for American products and manufacture more cheaply. His reasoning is quite simple, but very shortsighted. It won't succeed because, by doing so, Trump is missing a golden opportunity to modernize American industry.

I am critical of the fact that Hungarian Prime Minister Viktor Orbán is pulling out of everything - the joint approach to the refugee issue, for example. He cannot disparage his colleagues in the EU either - that's not how we treat each other. We require solidarity: in refugee policies, just as in the financial architecture of the structural funds from which countries like Hungary have strongly profited from for years.

In all of my speeches I talk about why a strong Europe is necessary in order for Germany to be strong over the long term. I think that I have sufficiently shown over the past years that I have a clear notion of how we can make Europe stronger, more democratic and more inclusive. There is really no competition there with Sigmar Gabriel.

I am grateful to the Germans in general, particularly those who displayed unending dedication to the refugees and who continue to do so.

I believe it is wrong to give Moscow a rebate on Ukraine sanctions because of Syria.

I find it surprising, however, that many German politicians generally oppose referendums, but then when it's an EU matter, they immediately scream for a plebiscite.

Things are going well in Germany because the economy is booming and as an export-driven nation, we are profiting from the fact that we have an excellent, high-performing SME sector. But if we want things to continue to go well into the future, then we have to break up the antiquated structures in some areas and really modernize.
